+Welcome to PDCurses!
+====================
+
+PDCurses is an implementation of X/Open curses for multiple platforms.
+The latest version can be found at:
+
+ https://pdcurses.org/
+
+For changes, see the [History] file. The main documentation is now in
+the [docs] directory.
+
+
+Legal Stuff
+-----------
+
+The core package is in the public domain, but small portions of PDCurses
+are subject to copyright under various licenses. Each directory
+contains a README.md file, with a section titled "Distribution Status"
+which describes the status of the files in that directory.
+
+If you use PDCurses in an application, an acknowledgement would be
+appreciated, but is not mandatory. If you make corrections or
+enhancements to PDCurses, please forward them to the current maintainer
+for the benefit of other users.
+
+This software is provided AS IS with NO WARRANTY whatsoever.
+
+
+Ports
+-----
+
+PDCurses has been ported to DOS, OS/2, Windows, X11 and SDL. A directory
+containing the port-specific source files exists for each of these
+platforms.
+
+Build instructions are in the README.md file for each platform:
+
+- [DOS]
+- [OS/2]
+- [SDL 1.x]
+- [SDL 2.x]
+- [Windows]
+- [X11]
+
+
+Distribution Status
+-------------------
+
+All files in this directory (not including subdirectories) are released
+to the public domain.

+ color pair | modifiers | character eg 'a'
+
+There are 256 color pairs (8 bits), 8 bits for modifiers, and 16 bits
+for character data. The modifiers are bold, underline, right-line,
+left-line, italic, reverse and blink, plus the alternate character set
+indicator.

+ int wecho_wchar(WINDOW *win, const cchar_t *wch);
+
+### Description
+
+ addch() adds the chtype ch to the default window (stdscr) at the
+ current cursor position, and advances the cursor. Note that chtypes
+ can convey both text (a single character) and attributes, including a
+ color pair. add_wch() is the wide-character version of this function,
+ taking a pointer to a cchar_t instead of a chtype.
+
+ waddch() is like addch(), but also lets you specify the window. (This
+ is in fact the core output routine.) wadd_wch() is the wide version.
+
+ mvaddch() moves the cursor to the specified (y, x) position, and adds
+ ch to stdscr. mvadd_wch() is the wide version.
+
+ mvwaddch() moves the cursor to the specified position and adds ch to
+ the specified window. mvwadd_wch() is the wide version.
+
+ echochar() adds ch to stdscr at the current cursor position and calls
+ refresh(). echo_wchar() is the wide version.
+
+ wechochar() adds ch to the specified window and calls wrefresh().
+ wecho_wchar() is the wide version.
+
+ addrawch(), waddrawch(), mvaddrawch() and mvwaddrawch() are PDCurses-
+ specific wrappers for addch() etc. that disable the translation of
+ control characters.
+
+ The following applies to all these functions:
+
+ If the cursor moves on to the right margin, an automatic newline is
+ performed. If scrollok is enabled, and a character is added to the
+ bottom right corner of the window, the scrolling region will be
+ scrolled up one line. If scrolling is not allowed, ERR will be
+ returned.
+
+ If ch is a tab, newline, or backspace, the cursor will be moved
+ appropriately within the window. If ch is a newline, the clrtoeol
+ routine is called before the cursor is moved to the beginning of the
+ next line. If newline mapping is off, the cursor will be moved to
+ the next line, but the x coordinate will be unchanged. If ch is a
+ tab the cursor is moved to the next tab position within the window.
+ If ch is another control character, it will be drawn in the ^X
+ notation. Calling the inch() routine after adding a control
+ character returns the representation of the control character, not
+ the control character.
+
+ Video attributes can be combined with a character by ORing them into
+ the parameter. Text, including attributes, can be copied from one
+ place to another by using inch() and addch().
+
+ Note that in PDCurses, for now, a cchar_t and a chtype are the same.
+ The text field is 16 bits wide, and is treated as Unicode (UCS-2)
+ when PDCurses is built with wide-character support (define PDC_WIDE).
+ So, in functions that take a chtype, like addch(), both the wide and
+ narrow versions will handle Unicode. But for portability, you should
+ use the wide functions.
+
+### Return Value
+
+ All functions return OK on success and ERR on error.

+
+### Description
+
+ These routines write all the characters of the null-terminated string
+ str or wide-character string wstr to the given window. The
+ functionality is similar to calling waddch() once for each character
+ in the string; except that, when PDCurses is built with wide-
+ character support enabled, the narrow-character functions treat the
+ string as a multibyte string in the current locale, and convert it.
+ The routines with n as the last argument write at most n characters;
+ if n is negative, then the entire string will be added.
+
+### Return Value
+
+ All functions return OK or ERR.

+### Description
+
+ These functions manipulate the current attributes and/or colors of
+ the named window. These attributes can be any combination of
+ A_STANDOUT, A_REVERSE, A_BOLD, A_DIM, A_BLINK, A_UNDERLINE. These
+ constants are defined in <curses.h> and can be combined with the
+ bitwise-OR operator (|).
+
+ The current attributes of a window are applied to all chtypes that
+ are written into the window with waddch(). Attributes are a property
+ of the chtype, and move with the character through any scrolling or
+ insert/delete operations.
+
+ wattrset() sets the current attributes of the given window to attrs.
+ attrset() is the stdscr version.
+
+ wattroff() turns off the named attributes without affecting any other
+ attributes; wattron() turns them on.
+
+ wcolor_set() sets the window color to the value of color_pair. opts
+ is unused.
+
+ standout() is the same as attron(A_STANDOUT). standend() is the same
+ as attrset(A_NORMAL); that is, it turns off all attributes.
+
+ The attr_* and wattr_* functions are intended for use with the WA_*
+ attributes. In PDCurses, these are the same as A_*, and there is no
+ difference in bevahior from the chtype-based functions. In all cases,
+ opts is unused.
+
+ wattr_get() retrieves the attributes and color pair for the specified
+ window.
+
+ wchgat() sets the color pair and attributes for the next n cells on
+ the current line of a given window, without changing the existing
+ text, or alterting the window's attributes. An n of -1 extends the
+ change to the edge of the window. The changes take effect
+ immediately. opts is unused.
+
+ wunderscore() turns on the A_UNDERLINE attribute; wunderend() turns
+ it off. underscore() and underend() are the stdscr versions.

+ int wgetbkgrnd(WINDOW *win, cchar_t *wch);
+
+### Description
+
+ bkgdset() and wbkgdset() manipulate the background of a window. The
+ background is a chtype consisting of any combination of attributes
+ and a character; it is combined with each chtype added or inserted to
+ the window by waddch() or winsch(). Only the attribute part is used
+ to set the background of non-blank characters, while both character
+ and attributes are used for blank positions.
+
+ bkgd() and wbkgd() not only change the background, but apply it
+ immediately to every cell in the window.
+
+ wbkgrnd(), wbkgrndset() and wgetbkgrnd() are the "wide-character"
+ versions of these functions, taking a pointer to a cchar_t instead of
+ a chtype. However, in PDCurses, cchar_t and chtype are the same.
+
+ The attributes that are defined with the attrset()/attron() set of
+ functions take precedence over the background attributes if there is
+ a conflict (e.g., different color pairs).
+
+### Return Value
+
+ bkgd() and wbkgd() return OK, unless the window is NULL, in which
+ case they return ERR.

+### Description
+
+ border(), wborder(), and box() draw a border around the edge of the
+ window. If any argument is zero, an appropriate default is used:
+
+ ls left side of border ACS_VLINE
+ rs right side of border ACS_VLINE
+ ts top side of border ACS_HLINE
+ bs bottom side of border ACS_HLINE
+ tl top left corner of border ACS_ULCORNER
+ tr top right corner of border ACS_URCORNER
+ bl bottom left corner of border ACS_LLCORNER
+ br bottom right corner of border ACS_LRCORNER
+
+ hline() and whline() draw a horizontal line, using ch, starting from
+ the current cursor position. The cursor position does not change. The
+ line is at most n characters long, or as many as will fit in the
+ window.
+
+ vline() and wvline() draw a vertical line, using ch, starting from
+ the current cursor position. The cursor position does not change. The
+ line is at most n characters long, or as many as will fit in the
+ window.
+
+ The *_set functions are the "wide-character" versions, taking
+ pointers to cchar_t instead of chtype. Note that in PDCurses, chtype
+ and cchar_t are the same.

+ int PDC_set_line_color(short color);
+
+### Description
+
+ To use these routines, first, call start_color(). Colors are always
+ used in pairs, referred to as color-pairs. A color-pair is created by
+ init_pair(), and consists of a foreground color and a background
+ color. After initialization, COLOR_PAIR(n) can be used like any other
+ video attribute.
+
+ has_colors() reports whether the terminal supports color.
+
+ start_color() initializes eight basic colors (black, red, green,
+ yellow, blue, magenta, cyan, and white), and two global variables:
+ COLORS and COLOR_PAIRS (respectively defining the maximum number of
+ colors and color-pairs the terminal is capable of displaying).
+
+ init_pair() changes the definition of a color-pair. It takes three
+ arguments: the number of the color-pair to be redefined, and the new
+ values of the foreground and background colors. The pair number must
+ be between 0 and COLOR_PAIRS - 1, inclusive. The foreground and
+ background must be between 0 and COLORS - 1, inclusive. If the color
+ pair was previously initialized, the screen is refreshed, and all
+ occurrences of that color-pair are changed to the new definition.
+
+ pair_content() is used to determine what the colors of a given color-
+ pair consist of.
+
+ can_change_color() indicates if the terminal has the capability to
+ change the definition of its colors.
+
+ init_color() is used to redefine a color, if possible. Each of the
+ components -- red, green, and blue -- is specified in a range from 0
+ to 1000, inclusive.
+
+ color_content() reports the current definition of a color in the same
+ format as used by init_color().
+
+ assume_default_colors() and use_default_colors() emulate the ncurses
+ extensions of the same names. assume_default_colors(f, b) is
+ essentially the same as init_pair(0, f, b) (which isn't allowed); it
+ redefines the default colors. use_default_colors() allows the use of
+ -1 as a foreground or background color with init_pair(), and calls
+ assume_default_colors(-1, -1); -1 represents the foreground or
+ background color that the terminal had at startup. If the environment
+ variable PDC_ORIGINAL_COLORS is set at the time start_color() is
+ called, that's equivalent to calling use_default_colors().
+
+ alloc_pair(), find_pair() and free_pair() are also from ncurses.
+ free_pair() marks a pair as unused; find_pair() returns an existing
+ pair with the specified foreground and background colors, if one
+ exists. And alloc_pair() returns such a pair whether or not it was
+ previously set, overwriting the oldest initialized pair if there are
+ no free pairs.
+
+ PDC_set_line_color() is used to set the color, globally, for the
+ color of the lines drawn for the attributes: A_UNDERLINE, A_LEFT and
+ A_RIGHT. A value of -1 (the default) indicates that the current
+ foreground color should be used.
+
+ NOTE: COLOR_PAIR() and PAIR_NUMBER() are implemented as macros.
+
+### Return Value
+
+ Most functions return OK on success and ERR on error. has_colors()
+ and can_change_colors() return TRUE or FALSE. alloc_pair() and
+ find_pair() return a pair number, or -1 on error.

+### Description
+
+ traceon() and traceoff() toggle the recording of debugging
+ information to the file "trace". Although not standard, similar

+
+ The environment variable PDC_TRACE_FLUSH controls whether the trace
+ file contents are fflushed after each write. The default is not. Set
+ it to enable this (may affect performance).

+
+### Description
+
+ With the getch(), wgetch(), mvgetch(), and mvwgetch() functions, a
+ character is read from the terminal associated with the window. In
+ nodelay mode, if there is no input waiting, the value ERR is
+ returned. In delay mode, the program will hang until the system
+ passes text through to the program. Depending on the setting of
+ cbreak(), this will be after one character or after the first
+ newline. Unless noecho() has been set, the character will also be
+ echoed into the designated window.
+
+ If keypad() is TRUE, and a function key is pressed, the token for
+ that function key will be returned instead of the raw characters.
+ Possible function keys are defined in <curses.h> with integers
+ beginning with 0401, whose names begin with KEY_.
+
+ If nodelay(win, TRUE) has been called on the window and no input is
+ waiting, the value ERR is returned.
+
+ ungetch() places ch back onto the input queue to be returned by the
+ next call to wgetch().
+
+ flushinp() throws away any type-ahead that has been typed by the user
+ and has not yet been read by the program.
+
+ wget_wch() is the wide-character version of wgetch(), available when
+ PDCurses is built with the PDC_WIDE option. It takes a pointer to a
+ wint_t rather than returning the key as an int, and instead returns
+ KEY_CODE_YES if the key is a function key. Otherwise, it returns OK
+ or ERR. It's important to check for KEY_CODE_YES, since regular wide
+ characters can have the same values as function key codes.
+
+ unget_wch() puts a wide character on the input queue.
+
+ PDC_get_key_modifiers() returns the keyboard modifiers (shift,
+ control, alt, numlock) effective at the time of the last getch()
+ call. Use the macros PDC_KEY_MODIFIER_* to determine which
+ modifier(s) were set. PDC_return_key_modifiers() tells getch() to
+ return modifier keys pressed alone as keystrokes (KEY_ALT_L, etc.).
+ These may not work on all platforms.
+
+ NOTE: getch() and ungetch() are implemented as macros, to avoid
+ conflict with many DOS compiler's runtime libraries.
+
+### Return Value
+
+ These functions return ERR or the value of the character, meta
+ character or function key token.

+
+### Description
+
+ These routines call wgetch() repeatedly to build a string,
+ interpreting erase and kill characters along the way, until a newline
+ or carriage return is received. When PDCurses is built with wide-
+ character support enabled, the narrow-character functions convert the
+ wgetch()'d values into a multibyte string in the current locale
+ before returning it. The resulting string is placed in the area
+ pointed to by *str. The routines with n as the last argument read at
+ most n characters.
+
+ Note that there's no way to know how long the buffer passed to
+ wgetstr() is, so use wgetnstr() to avoid buffer overflows.
+
+### Return Value
+
+ These functions return ERR on failure or any other value on success.

+
+### Description
+
+ The getyx() macro (defined in curses.h -- the prototypes here are
+ merely illustrative) puts the current cursor position of the
+ specified window into y and x. getbegyx() and getmaxyx() return the
+ starting coordinates and size of the specified window, respectively.
+ getparyx() returns the starting coordinates of the parent's window,
+ if the specified window is a subwindow; otherwise it sets y and x to
+ -1. These are all macros.
+
+ getsyx() gets the coordinates of the virtual screen cursor, and
+ stores them in y and x. If leaveok() is TRUE, it returns -1, -1. If
+ lines have been removed with ripoffline(), then getsyx() includes
+ these lines in its count; so, the returned y and x values should only
+ be used with setsyx().
+
+ setsyx() sets the virtual screen cursor to the y, x coordinates. If
+ either y or x is -1, leaveok() is set TRUE, else it's set FALSE.
+
+ getsyx() and setsyx() are meant to be used by a library routine that
+ manipulates curses windows without altering the position of the
+ cursor. Note that getsyx() is defined only as a macro.
+
+ getbegy(), getbegx(), getcurx(), getcury(), getmaxy(), getmaxx(),
+ getpary(), and getparx() return the appropriate coordinate or size
+ values, or ERR in the case of a NULL window.

+
+### Description
+
+ initscr() should be the first curses routine called. It will
+ initialize all curses data structures, and arrange that the first
+ call to refresh() will clear the screen. In case of error, initscr()
+ will write a message to standard error and end the program.
+
+ endwin() should be called before exiting or escaping from curses mode
+ temporarily. It will restore tty modes, move the cursor to the lower
+ left corner of the screen and reset the terminal into the proper
+ non-visual mode. To resume curses after a temporary escape, call
+ refresh() or doupdate().
+
+ isendwin() returns TRUE if endwin() has been called without a
+ subsequent refresh, unless SP is NULL.
+
+ In some implementations of curses, newterm() allows the use of
+ multiple terminals. Here, it's just an alternative interface for
+ initscr(). It always returns SP, or NULL.
+
+ delscreen() frees the memory allocated by newterm() or initscr(),
+ since it's not freed by endwin(). This function is usually not
+ needed. In PDCurses, the parameter must be the value of SP, and
+ delscreen() sets SP to NULL.
+
+ set_term() does nothing meaningful in PDCurses, but is included for
+ compatibility with other curses implementations.
+
+ resize_term() is effectively two functions: When called with nonzero
+ values for nlines and ncols, it attempts to resize the screen to the
+ given size. When called with (0, 0), it merely adjusts the internal
+ structures to match the current size after the screen is resized by
+ the user. On the currently supported platforms, SDL, Windows console,
+ and X11 allow user resizing, while DOS, OS/2, SDL and Windows console
+ allow programmatic resizing. If you want to support user resizing,
+ you should check for getch() returning KEY_RESIZE, and/or call
+ is_termresized() at appropriate times; if either condition occurs,
+ call resize_term(0, 0). Then, with either user or programmatic
+ resizing, you'll have to resize any windows you've created, as
+ appropriate; resize_term() only handles stdscr and curscr.
+
+ is_termresized() returns TRUE if the curses screen has been resized
+ by the user, and a call to resize_term() is needed. Checking for
+ KEY_RESIZE is generally preferable, unless you're not handling the
+ keyboard.
+
+ curses_version() returns a string describing the version of PDCurses.
+
+ PDC_get_version() fills a PDC_VERSION structure provided by the user
+ with more detailed version info (see curses.h).
+
+ set_tabsize() sets the tab interval, stored in TABSIZE.
+
+### Return Value
+
+ All functions return NULL on error, except endwin(), which always
+ returns OK, and resize_term(), which returns either OK or ERR.

+
+### Description
+
+ cbreak() and nocbreak() toggle cbreak mode. In cbreak mode,
+ characters typed by the user are made available immediately, and
+ erase/kill character processing is not performed. In nocbreak mode,
+ typed characters are buffered until a newline or carriage return.
+ Interrupt and flow control characters are unaffected by this mode.
+ PDCurses always starts in cbreak mode.
+
+ echo() and noecho() control whether typed characters are echoed by
+ the input routine. Initially, input characters are echoed. Subsequent
+ calls to echo() and noecho() do not flush type-ahead.
+
+ halfdelay() is similar to cbreak(), but allows for a time limit to be
+ specified, in tenths of a second. This causes getch() to block for
+ that period before returning ERR if no key has been received. tenths
+ must be between 1 and 255.
+
+ keypad() controls whether getch() returns function/special keys as
+ single key codes (e.g., the left arrow key as KEY_LEFT). Per X/Open,
+ the default for keypad mode is OFF. You'll probably want it on. With
+ keypad mode off, if a special key is pressed, getch() does nothing or
+ returns ERR.
+
+ nodelay() controls whether wgetch() is a non-blocking call. If the
+ option is enabled, and no input is ready, wgetch() will return ERR.
+ If disabled, wgetch() will hang until input is ready.
+
+ nl() enables the translation of a carriage return into a newline on
+ input. nonl() disables this. Initially, the translation does occur.
+
+ raw() and noraw() toggle raw mode. Raw mode is similar to cbreak
+ mode, in that characters typed are immediately passed through to the
+ user program. The difference is that in raw mode, the INTR, QUIT,
+ SUSP, and STOP characters are passed through without being
+ interpreted, and without generating a signal.
+
+ In PDCurses, the meta() function sets raw mode on or off.
+
+ timeout() and wtimeout() set blocking or non-blocking reads for the
+ specified window. If the delay is negative, a blocking read is used;
+ if zero, then non-blocking reads are done -- if no input is waiting,
+ ERR is returned immediately. If the delay is positive, the read
+ blocks for the delay period; if the period expires, ERR is returned.
+ The delay is given in milliseconds, but this is rounded down to 50ms
+ (1/20th sec) intervals, with a minimum of one interval if a postive
+ delay is given; i.e., 1-99 will wait 50ms, 100-149 will wait 100ms,
+ etc.
+
+ intrflush(), notimeout(), noqiflush(), qiflush() and typeahead() do
+ nothing in PDCurses, but are included for compatibility with other
+ curses implementations.
+
+ crmode() and nocrmode() are archaic equivalents to cbreak() and
+ nocbreak(), respectively.
+
+ is_keypad() reports whether the specified window is in keypad mode.
+
+### Return Value

+ success and ERR on error.

+
+ The ins_wch() functions are the wide-character equivalents, taking

+
+### Description
+
+ The insstr() functions insert a character string into a window at the
+ current cursor position, by repeatedly calling winsch(). When
+ PDCurses is built with wide-character support enabled, the narrow-
+ character functions treat the string as a multibyte string in the
+ current locale, and convert it first. All characters to the right of
+ the cursor are moved to the right, with the possibility of the
+ rightmost characters on the line being lost. The cursor position
+ does not change (after moving to y, x, if specified). The routines
+ with n as the last argument insert at most n characters; if n is
+ negative, then the entire string is inserted.
+
+### Return Value
+
+ All functions return OK on success and ERR on error.

+
+### Description
+
+ def_prog_mode() and def_shell_mode() save the current terminal modes
+ as the "program" (in curses) or "shell" (not in curses) state for use
+ by the reset_prog_mode() and reset_shell_mode() functions. This is
+ done automatically by initscr().
+
+ reset_prog_mode() and reset_shell_mode() restore the terminal to
+ "program" (in curses) or "shell" (not in curses) state. These are
+ done automatically by endwin() and doupdate() after an endwin(), so
+ they would normally not be called before these functions.
+
+ savetty() and resetty() save and restore the state of the terminal
+ modes. savetty() saves the current state in a buffer, and resetty()
+ restores the state to what it was at the last call to savetty().
+
+ curs_set() alters the appearance of the cursor. A visibility of 0
+ makes it disappear; 1 makes it appear "normal" (usually an underline)
+ and 2 makes it "highly visible" (usually a block).
+
+ ripoffline() reduces the size of stdscr by one line. If the "line"
+ parameter is positive, the line is removed from the top of the
+ screen; if negative, from the bottom. Up to 5 lines can be ripped off
+ stdscr by calling ripoffline() repeatedly. The function argument,
+ init, is called from within initscr() or newterm(), so ripoffline()
+ must be called before either of these functions. The init function
+ receives a pointer to a one-line WINDOW, and the width of the window.
+ Calling ripoffline() with a NULL init function pointer is an error.
+
+ napms() suspends the program for the specified number of
+ milliseconds. draino() is an archaic equivalent. Note that since
+ napms() attempts to give up a time slice and yield control back to
+ the OS, all times are approximate. (In DOS, the delay is actually
+ rounded down to 50ms (1/20th sec) intervals, with a minimum of one
+ interval; i.e., 1-99 will wait 50ms, 100-149 will wait 100ms, etc.)
+ 0 returns immediately.
+
+ resetterm(), fixterm() and saveterm() are archaic equivalents for
+ reset_shell_mode(), reset_prog_mode() and def_prog_mode(),
+ respectively.
+
+### Return Value
+
+ All functions return OK on success and ERR on error, except
+ curs_set(), which returns the previous visibility.

+
+### Description
+
+ As of PDCurses 3.0, there are two separate mouse interfaces: the
+ classic interface, which is based on the undocumented Sys V mouse
+ functions; and an ncurses-compatible interface. Both are active at
+ all times, and you can mix and match functions from each, though it's
+ not recommended. The ncurses interface is essentially an emulation
+ layer built on top of the classic interface; it's here to allow
+ easier porting of ncurses apps.
+
+ The classic interface: mouse_set(), mouse_on(), mouse_off(),
+ request_mouse_pos(), wmouse_position(), and getmouse(). An
+ application using this interface would start by calling mouse_set()
+ or mouse_on() with a non-zero value, often ALL_MOUSE_EVENTS. Then it
+ would check for a KEY_MOUSE return from getch(). If found, it would
+ call request_mouse_pos() to get the current mouse status.
+
+ mouse_set(), mouse_on() and mouse_off() are analagous to attrset(),
+ attron() and attroff(). These functions set the mouse button events
+ to trap. The button masks used in these functions are defined in
+ curses.h and can be or'ed together. They are the group of masks
+ starting with BUTTON1_RELEASED.
+
+ request_mouse_pos() requests curses to fill in the Mouse_status
+ structure with the current state of the mouse.
+
+ wmouse_position() determines if the current mouse position is within
+ the window passed as an argument. If the mouse is outside the current
+ window, -1 is returned in the y and x arguments; otherwise the y and
+ x coordinates of the mouse (relative to the top left corner of the
+ window) are returned in y and x.
+
+ getmouse() returns the current status of the trapped mouse buttons as
+ set by mouse_set() or mouse_on().
+
+ The ncurses interface: mouseinterval(), wenclose(), wmouse_trafo(),
+ mouse_trafo(), mousemask(), nc_getmouse(), ungetmouse() and
+ has_mouse(). A typical application using this interface would start
+ by calling mousemask() with a non-zero value, often ALL_MOUSE_EVENTS.
+ Then it would check for a KEY_MOUSE return from getch(). If found, it
+ would call nc_getmouse() to get the current mouse status.
+
+ mouseinterval() sets the timeout for a mouse click. On all current
+ platforms, PDCurses receives mouse button press and release events,
+ but must synthesize click events. It does this by checking whether a
+ release event is queued up after a press event. If it gets a press
+ event, and there are no more events waiting, it will wait for the
+ timeout interval, then check again for a release. A press followed by
+ a release is reported as BUTTON_CLICKED; otherwise it's passed
+ through as BUTTON_PRESSED. The default timeout is 150ms; valid values
+ are 0 (no clicks reported) through 1000ms. In x11, the timeout can
+ also be set via the clickPeriod resource. The return value from
+ mouseinterval() is the old timeout. To check the old value without
+ setting a new one, call it with a parameter of -1. Note that although
+ there's no classic equivalent for this function (apart from the
+ clickPeriod resource), the value set applies in both interfaces.
+
+ wenclose() reports whether the given screen-relative y, x coordinates
+ fall within the given window.
+
+ wmouse_trafo() converts between screen-relative and window-relative
+ coordinates. A to_screen parameter of TRUE means to convert from
+ window to screen; otherwise the reverse. The function returns FALSE
+ if the coordinates aren't within the window, or if any of the
+ parameters are NULL. The coordinates have been converted when the
+ function returns TRUE.
+
+ mouse_trafo() is the stdscr version of wmouse_trafo().
+
+ mousemask() is nearly equivalent to mouse_set(), but instead of
+ OK/ERR, it returns the value of the mask after setting it. (This
+ isn't necessarily the same value passed in, since the mask could be
+ altered on some platforms.) And if the second parameter is a non-null
+ pointer, mousemask() stores the previous mask value there. Also,
+ since the ncurses interface doesn't work with PDCurses' BUTTON_MOVED
+ events, mousemask() filters them out.
+
+ nc_getmouse() returns the current mouse status in an MEVENT struct.
+ This is equivalent to ncurses' getmouse(), renamed to avoid conflict
+ with PDCurses' getmouse(). But if you define PDC_NCMOUSE before
+ including curses.h, it defines getmouse() to nc_getmouse(), along
+ with a few other redefintions needed for compatibility with ncurses
+ code. nc_getmouse() calls request_mouse_pos(), which (not getmouse())
+ is the classic equivalent.
+
+ ungetmouse() is the mouse equivalent of ungetch(). However, PDCurses
+ doesn't maintain a queue of mouse events; only one can be pushed
+ back, and it can overwrite or be overwritten by real mouse events.
+
+ has_mouse() reports whether the mouse is available at all on the
+ current platform.

+
+### Description
+
+ With clearok(), if bf is TRUE, the next call to wrefresh() with this
+ window will clear the screen completely and redraw the entire screen.
+
+ immedok(), called with a second argument of TRUE, causes an automatic
+ wrefresh() every time a change is made to the specified window.
+
+ Normally, the hardware cursor is left at the location of the window
+ being refreshed. leaveok() allows the cursor to be left wherever the
+ update happens to leave it. It's useful for applications where the
+ cursor is not used, since it reduces the need for cursor motions. If
+ possible, the cursor is made invisible when this option is enabled.
+
+ wsetscrreg() sets a scrolling region in a window; "top" and "bot" are
+ the line numbers for the top and bottom margins. If this option and
+ scrollok() are enabled, any attempt to move off the bottom margin
+ will cause all lines in the scrolling region to scroll up one line.
+ setscrreg() is the stdscr version.
+
+ idlok() and idcok() do nothing in PDCurses, but are provided for
+ compatibility with other curses implementations.
+
+ raw_output() enables the output of raw characters using the standard
+ *add* and *ins* curses functions (that is, it disables translation of
+ control characters).
+
+ is_leaveok() reports whether the specified window is in leaveok mode.

+
+### Description
+
+ overlay() and overwrite() copy all the text from src_w into dst_w.
+ The windows need not be the same size. Those characters in the source
+ window that intersect with the destination window are copied, so that
+ the characters appear in the same physical position on the screen.
+ The difference between the two functions is that overlay() is non-
+ destructive (blanks are not copied) while overwrite() is destructive
+ (blanks are copied).
+
+ copywin() is similar, but doesn't require that the two windows
+ overlap. The arguments src_tc and src_tr specify the top left corner
+ of the region to be copied. dst_tc, dst_tr, dst_br, and dst_bc
+ specify the region within the destination window to copy to. The
+ argument "overlay", if TRUE, indicates that the copy is done non-
+ destructively (as in overlay()); blanks in the source window are not
+ copied to the destination window. When overlay is FALSE, blanks are
+ copied.

+
+### Description
+
+ A pad is a special kind of window, which is not restricted by the
+ screen size, and is not necessarily associated with a particular part
+ of the screen. You can use a pad when you need a large window, and
+ only a part of the window will be on the screen at one time. Pads are
+ not refreshed automatically (e.g., from scrolling or echoing of
+ input). You can't call wrefresh() with a pad as an argument; use
+ prefresh() or pnoutrefresh() instead. Note that these routines
+ require additional parameters to specify the part of the pad to be
+ displayed, and the location to use on the screen.
+
+ newpad() creates a new pad data structure.
+
+ subpad() creates a new sub-pad within a pad, at position (begy,
+ begx), with dimensions of nlines lines and ncols columns. This
+ position is relative to the pad, and not to the screen as with
+ subwin. Changes to either the parent pad or sub-pad will affect both.
+ When using sub-pads, you may need to call touchwin() before calling
+ prefresh().
+
+ pnoutrefresh() copies the specified pad to the virtual screen.
+
+ prefresh() calls pnoutrefresh(), followed by doupdate().
+
+ These routines are analogous to wnoutrefresh() and wrefresh(). (py,
+ px) specifies the upper left corner of the part of the pad to be
+ displayed; (sy1, sx1) and (sy2, sx2) describe the screen rectangle
+ that will contain the selected part of the pad.
+
+ pechochar() is functionally equivalent to addch() followed by a call
+ to prefresh(), with the last-used coordinates and dimensions.
+ pecho_wchar() is the wide-character version.
+
+ is_pad() reports whether the specified window is a pad.

+
+### Description
+
+ For historic reasons, and for compatibility with other versions of
+ curses, the panel functions are prototyped in a separate header,
+ panel.h. In many implementations, they're also in a separate library,
+ but PDCurses incorporates them.
+
+ The panel functions provide a way to have depth relationships between
+ curses windows. Panels can overlap without making visible the
+ overlapped portions of underlying windows. The initial curses window,
+ stdscr, lies beneath all panels. The set of currently visible panels
+ is the 'deck' of panels.
+
+ You can create panels, fetch and set their associated windows,
+ shuffle panels in the deck, and manipulate them in other ways.
+
+ bottom_panel() places pan at the bottom of the deck. The size,
+ location and contents of the panel are unchanged.
+
+ del_panel() deletes pan, but not its associated winwow.
+
+ hide_panel() removes a panel from the deck and thus hides it from
+ view.
+
+ move_panel() moves the curses window associated with pan, so that its
+ upper lefthand corner is at the supplied coordinates. (Don't use
+ mvwin() on the window.)
+
+ new_panel() creates a new panel associated with win and returns the
+ panel pointer. The new panel is placed at the top of the deck.
+
+ panel_above() returns a pointer to the panel in the deck above pan,
+ or NULL if pan is the top panel. If the value of pan passed is NULL,
+ this function returns a pointer to the bottom panel in the deck.
+
+ panel_below() returns a pointer to the panel in the deck below pan,
+ or NULL if pan is the bottom panel. If the value of pan passed is
+ NULL, this function returns a pointer to the top panel in the deck.
+
+ panel_hidden() returns OK if pan is hidden and ERR if it is not.
+
+ panel_userptr() - Each panel has a user pointer available for
+ maintaining relevant information. This function returns a pointer to
+ that information previously set up by set_panel_userptr().
+
+ panel_window() returns a pointer to the curses window associated with
+ the panel.
+
+ replace_panel() replaces the current window of pan with win.
+
+ set_panel_userptr() - Each panel has a user pointer available for
+ maintaining relevant information. This function sets the value of
+ that information.
+
+ show_panel() makes a previously hidden panel visible and places it
+ back in the deck on top.
+
+ top_panel() places pan on the top of the deck. The size, location and
+ contents of the panel are unchanged.

+ update_panels() refreshes the virtual screen to reflect the depth
+ relationships between the panels in the deck. The user must use
+ doupdate() to refresh the physical screen.
+
+### Return Value
+
+ Each routine that returns a pointer to an object returns NULL if an
+ error occurs. Each panel routine that returns an integer, returns OK
+ if it executes successfully and ERR if it does not.

+### Description
+
+ The printw() functions add a formatted string to the window at the

+
+### Synopsis
+
+ int refresh(void);
+ int wrefresh(WINDOW *win);
+ int wnoutrefresh(WINDOW *win);
+ int doupdate(void);
+ int redrawwin(WINDOW *win);
+ int wredrawln(WINDOW *win, int beg_line, int num_lines);
+
+### Description
+
+ wrefresh() copies the named window to the physical terminal screen,
+ taking into account what is already there in order to optimize cursor
+ movement. refresh() does the same, using stdscr. These routines must
+ be called to get any output on the terminal, as other routines only
+ manipulate data structures. Unless leaveok() has been enabled, the
+ physical cursor of the terminal is left at the location of the
+ window's cursor.
+
+ wnoutrefresh() and doupdate() allow multiple updates with more
+ efficiency than wrefresh() alone. wrefresh() works by first calling
+ wnoutrefresh(), which copies the named window to the virtual screen.
+ It then calls doupdate(), which compares the virtual screen to the
+ physical screen and does the actual update. A series of calls to
+ wrefresh() will result in alternating calls to wnoutrefresh() and
+ doupdate(), causing several bursts of output to the screen. By first
+ calling wnoutrefresh() for each window, it is then possible to call
+ doupdate() only once.
+
+ In PDCurses, redrawwin() is equivalent to touchwin(), and wredrawln()
+ is the same as touchline(). In some other curses implementations,
+ there's a subtle distinction, but it has no meaning in PDCurses.
+
+### Return Value

+### Synopsis
+
+ int scanw(const char *fmt, ...);
+ int wscanw(WINDOW *win, const char *fmt, ...);
+ int mvscanw(int y, int x, const char *fmt, ...);
+ int mvwscanw(WINDOW *win, int y, int x, const char *fmt, ...);
+ int vwscanw(WINDOW *win, const char *fmt, va_list varglist);
+ int vw_scanw(WINDOW *win, const char *fmt, va_list varglist);
+
+### Description
+
+ These routines correspond to the standard C library's scanf() family.
+ Each gets a string from the window via wgetnstr(), and uses the
+ resulting line as input for the scan.
+
+ The duplication between vwscanw() and vw_scanw() is for historic
+ reasons. In PDCurses, they're the same.
+
+### Return Value
+
+ On successful completion, these functions return the number of items
+ successfully matched. Otherwise they return ERR.

+--------
+
+### Synopsis
+
+ int putwin(WINDOW *win, FILE *filep);
+ WINDOW *getwin(FILE *filep);
+ int scr_dump(const char *filename);
+ int scr_init(const char *filename);
+ int scr_restore(const char *filename);
+ int scr_set(const char *filename);
+
+### Description
+
+ getwin() reads window-related data previously stored in a file by
+ putwin(). It then creates and initialises a new window using that
+ data.
+
+ putwin() writes all data associated with a window into a file, using
+ an unspecified format. This information can be retrieved later using
+ getwin().
+
+ scr_dump() writes the current contents of the virtual screen to the
+ file named by filename in an unspecified format.
+
+ scr_restore() function sets the virtual screen to the contents of the
+ file named by filename, which must have been written using
+ scr_dump(). The next refresh operation restores the screen to the way
+ it looked in the dump file.
+
+ In PDCurses, scr_init() does nothing, and scr_set() is a synonym for
+ scr_restore(). Also, scr_dump() and scr_restore() save and load from
+ curscr. This differs from some other implementations, where
+ scr_init() works with curscr, and scr_restore() works with newscr;
+ but the effect should be the same. (PDCurses has no newscr.)
+
+### Return Value
+
+ On successful completion, getwin() returns a pointer to the window it
+ created. Otherwise, it returns a null pointer. Other functions return
+ OK or ERR.

+
+### Description
+
+ These functions manipulate a window that contain Soft Label Keys
+ (SLK). To use the SLK functions, a call to slk_init() must be made
+ BEFORE initscr() or newterm(). slk_init() removes 1 or 2 lines from
+ the useable screen, depending on the format selected.
+
+ The line(s) removed from the screen are used as a separate window, in
+ which SLKs are displayed.
+
+ slk_init() requires a single parameter which describes the format of
+ the SLKs as follows:
+
+ 0 3-2-3 format
+ 1 4-4 format
+ 2 4-4-4 format (ncurses extension)
+ 3 4-4-4 format with index line (ncurses extension)
+ 2 lines used
+ 55 5-5 format (pdcurses format)
+
+ slk_refresh(), slk_noutrefresh() and slk_touch() are analogous to
+ refresh(), noutrefresh() and touch().
+
+### Return Value
+
+ All functions return OK on success and ERR on error.

+
+### Description
+
+ baudrate() is supposed to return the output speed of the terminal. In
+ PDCurses, it simply returns INT_MAX.
+
+ has_ic and has_il() return TRUE. These functions have meaning in some
+ other implementations of curses.
+
+ erasechar() and killchar() return ^H and ^U, respectively -- the
+ ERASE and KILL characters. In other curses implementations, these may
+ vary by terminal type. erasewchar() and killwchar() are the wide-
+ character versions; they take a pointer to a location in which to
+ store the character, and return OK or ERR.
+
+ longname() returns a pointer to a static area containing a verbose
+ description of the current terminal. The maximum length of the string
+ is 128 characters. It is defined only after the call to initscr() or
+ newterm().
+
+ termname() returns a pointer to a static area containing a short
+ description of the current terminal (14 characters).
+
+ termattrs() returns a logical OR of all video attributes supported by
+ the terminal.
+
+ wordchar() is a PDCurses extension of the concept behind the
+ functions erasechar() and killchar(), returning the "delete word"
+ character, ^W.

+
+ int touchoverlap(const WINDOW *win1, WINDOW *win2);
+
+### Description
+
+ touchwin() and touchline() throw away all information about which
+ parts of the window have been touched, pretending that the entire
+ window has been drawn on. This is sometimes necessary when using
+ overlapping windows, since a change to one window will affect the
+ other window, but the records of which lines have been changed in the
+ other window will not reflect the change.
+
+ untouchwin() marks all lines in the window as unchanged since the
+ last call to wrefresh().
+
+ wtouchln() makes n lines in the window, starting at line y, look as
+ if they have (changed == 1) or have not (changed == 0) been changed
+ since the last call to wrefresh().
+
+ is_linetouched() returns TRUE if the specified line in the specified
+ window has been changed since the last call to wrefresh().
+
+ is_wintouched() returns TRUE if the specified window has been changed
+ since the last call to wrefresh().
+
+ touchoverlap(win1, win2) marks the portion of win2 which overlaps
+ with win1 as modified.
+
+### Return Value
+
+ All functions return OK on success and ERR on error except
+ is_wintouched() and is_linetouched().

+
+### Description
+
+ unctrl() expands the text portion of the chtype c into a printable
+ string. Control characters are changed to the "^X" notation; others
+ are passed through. wunctrl() is the wide-character version of the
+ function.
+
+ filter() and use_env() are no-ops in PDCurses.
+
+ delay_output() inserts an ms millisecond pause in output.
+
+ getcchar() works in two modes: When wch is not NULL, it reads the
+ cchar_t pointed to by wcval and stores the attributes in attrs, the
+ color pair in color_pair, and the text in the wide-character string
+ wch. When wch is NULL, getcchar() merely returns the number of wide
+ characters in wcval. In either mode, the opts argument is unused.
+
+ setcchar constructs a cchar_t at wcval from the wide-character text
+ at wch, the attributes in attr and the color pair in color_pair. The
+ opts argument is unused.
+
+ Currently, the length returned by getcchar() is always 1 or 0.
+ Similarly, setcchar() will only take the first wide character from
+ wch, and ignore any others that it "should" take (i.e., combining
+ characters). Nor will it correctly handle any character outside the
+ basic multilingual plane (UCS-2).
+
+### Return Value
+
+ wunctrl() returns NULL on failure. delay_output() always returns OK.
+
+ getcchar() returns the number of wide characters wcval points to when
+ wch is NULL; when it's not, getcchar() returns OK or ERR.
+
+ setcchar() returns OK or ERR.

+
+### Description
+
+ newwin() creates a new window with the given number of lines, nlines
+ and columns, ncols. The upper left corner of the window is at line
+ begy, column begx. If nlines is zero, it defaults to LINES - begy;
+ ncols to COLS - begx. Create a new full-screen window by calling
+ newwin(0, 0, 0, 0).
+
+ delwin() deletes the named window, freeing all associated memory. In
+ the case of overlapping windows, subwindows should be deleted before
+ the main window.
+
+ mvwin() moves the window so that the upper left-hand corner is at
+ position (y,x). If the move would cause the window to be off the
+ screen, it is an error and the window is not moved. Moving subwindows
+ is allowed.
+
+ subwin() creates a new subwindow within a window. The dimensions of
+ the subwindow are nlines lines and ncols columns. The subwindow is at
+ position (begy, begx) on the screen. This position is relative to the
+ screen, and not to the window orig. Changes made to either window
+ will affect both. When using this routine, you will often need to
+ call touchwin() before calling wrefresh().
+
+ derwin() is the same as subwin(), except that begy and begx are
+ relative to the origin of the window orig rather than the screen.
+ There is no difference between subwindows and derived windows.
+
+ mvderwin() moves a derived window (or subwindow) inside its parent
+ window. The screen-relative parameters of the window are not changed.
+ This routine is used to display different parts of the parent window
+ at the same physical position on the screen.
+
+ dupwin() creates an exact duplicate of the window win.
+
+ wsyncup() causes a touchwin() of all of the window's parents.
+
+ If wsyncok() is called with a second argument of TRUE, this causes a
+ wsyncup() to be called every time the window is changed.
+
+ wcursyncup() causes the current cursor position of all of a window's
+ ancestors to reflect the current cursor position of the current
+ window.
+
+ wsyncdown() causes a touchwin() of the current window if any of its
+ parent's windows have been touched.
+
+ resize_window() allows the user to resize an existing window. It
+ returns the pointer to the new window, or NULL on failure.
+
+ wresize() is an ncurses-compatible wrapper for resize_window(). Note
+ that, unlike ncurses, it will NOT process any subwindows of the
+ window. (However, you still can call it _on_ subwindows.) It returns
+ OK or ERR.
+
+ PDC_makenew() allocates all data for a new WINDOW * except the actual
+ lines themselves. If it's unable to allocate memory for the window
+ structure, it will free all allocated memory and return a NULL
+ pointer.
+
+ PDC_makelines() allocates the memory for the lines.
+
+ PDC_sync() handles wrefresh() and wsyncup() calls when a window is
+ changed.
+
+### Return Value
+
+ newwin(), subwin(), derwin() and dupwin() return a pointer to the new
+ window, or NULL on failure. delwin(), mvwin(), mvderwin() and
+ syncok() return OK or ERR. wsyncup(), wcursyncup() and wsyncdown()
+ return nothing.
+
+### Errors
+
+ It is an error to call resize_window() before calling initscr().
+ Also, an error will be generated if we fail to create a newly sized
+ replacement window for curscr, or stdscr. This could happen when
+ increasing the window size. NOTE: If this happens, the previously
+ successfully allocated windows are left alone; i.e., the resize is
+ NOT cancelled for those windows.

+PDCurses for Windows console
+============================
+
+This directory contains PDCurses source code files specific to the
+Microsoft Windows console. Although historically called "Win32", this
+port can just as easily be built for 64-bit systems. Windows 95 through
+Windows 10 are covered. (Some features require later versions.)
+
+
+Building
+--------
+
+- Choose the appropriate makefile for your compiler:
+
+ Makefile - GCC (MinGW or Cygnus)
+ Makefile.bcc - Borland C++
+ Makefile.vc - Microsoft Visual C++
+ Makefile.wcc - Watcom
+
+- Optionally, you can build in a different directory than the platform
+ directory by setting PDCURSES_SRCDIR to point to the directory where
+ you unpacked PDCurses, and changing to your target directory:
+
+ set PDCURSES_SRCDIR=c:\pdcurses
+
+- Build it:
+
+ make -f makefilename
+
+ (For Watcom, use "wmake" instead of "make"; for MSVC, "nmake"; for
+ MinGW, "mingw32-make".) You'll get the library (pdcurses.lib or .a,
+ depending on your compiler) and a lot of object files.
+
+ You can also give the optional parameter "WIDE=Y", to build the
+ library with wide-character (Unicode) support:
+
+ wmake -f Makefile.wcc WIDE=Y
+
+ When built this way, the library is not compatible with Windows 9x,
+ unless you also link with the Microsoft Layer for Unicode (not
+ tested).
+
+ Another option, "UTF8=Y", makes PDCurses ignore the system locale, and
+ treat all narrow-character strings as UTF-8. This option has no effect
+ unless WIDE=Y is also set. Use it to get around the poor support for
+ UTF-8 in the Windows console:
+
+ make -f Makefile.bcc WIDE=Y UTF8=Y
+
+ You can also use the optional parameter "DLL=Y" with Visual C++,
+ MinGW or Cygwin, to build the library as a DLL:
+
+ nmake -f Makefile.vc WIDE=Y DLL=Y
+
+ When you build the library as a Windows DLL, you must always define
+ PDC_DLL_BUILD when linking against it. (Or, if you only want to use
+ the DLL, you could add this definition to your curses.h.)
+
+ Add the target "demos" to build the sample programs.
+
+- If your build stops with errors about PCONSOLE_SCREEN_BUFFER_INFOEX,
+ add the parameter "INFOEX=N" to your make command line and try again.
+ (This will happen with older compile environments.)
+
+
+Distribution Status
+-------------------
+
+The files in this directory are released to the public domain.

+---------
+
+### Synopsis
+
+ int PDC_getclipboard(char **contents, long *length);
+ int PDC_setclipboard(const char *contents, long length);
+ int PDC_freeclipboard(char *contents);
+ int PDC_clearclipboard(void);
+
+### Description
+
+ PDC_getclipboard() gets the textual contents of the system's
+ clipboard. This function returns the contents of the clipboard in the
+ contents argument. It is the responsibility of the caller to free the
+ memory returned, via PDC_freeclipboard(). The length of the clipboard
+ contents is returned in the length argument.
+
+ PDC_setclipboard copies the supplied text into the system's
+ clipboard, emptying the clipboard prior to the copy.
+
+ PDC_clearclipboard() clears the internal clipboard.
+
+### Return Values
+
+ indicator of success/failure of call.
+ PDC_CLIP_SUCCESS the call was successful
+ PDC_CLIP_MEMORY_ERROR unable to allocate sufficient memory for
+ the clipboard contents
+ PDC_CLIP_EMPTY the clipboard contains no text
+ PDC_CLIP_ACCESS_ERROR no clipboard support

+### Synopsis
+
+ int PDC_set_blink(bool blinkon);
+ int PDC_set_bold(bool boldon);
+ void PDC_set_title(const char *title);
+
+### Description
+
+ PDC_set_blink() toggles whether the A_BLINK attribute sets an actual
+ blink mode (TRUE), or sets the background color to high intensity
+ (FALSE). The default is platform-dependent (FALSE in most cases). It
+ returns OK if it could set the state to match the given parameter,
+ ERR otherwise.
+
+ PDC_set_bold() toggles whether the A_BOLD attribute selects an actual
+ bold font (TRUE), or sets the foreground color to high intensity
+ (FALSE). It returns OK if it could set the state to match the given
+ parameter, ERR otherwise.
+
+ PDC_set_title() sets the title of the window in which the curses
+ program is running. This function may not do anything on some
+ platforms.
+
+### Portability
+ X/Open ncurses NetBSD
+ PDC_set_blink - - -
