+=head1 NAME
+
+Win32 - Interfaces to some Win32 API Functions
+
+=head1 DESCRIPTION
+
+Perl on Win32 contains several functions to access Win32 APIs.  Some
+are included in Perl itself (on Win32) and some are only available
+after explicitly requesting the Win32 module with:
+
+	use Win32;
+
+The builtin functions are marked as [CORE] and the other ones
+as [EXT] in the following alphabetical listing.
+
+=head2 Alphabetical Listing of Win32 Functions
+
+=over
+
+=item Win32::AbortSystemShutdown(MACHINE)
+
+[EXT] Aborts a system shutdown (started by the
+InitiateSystemShutdown function) on the specified MACHINE.
+
+=item Win32::BuildNumber()
+
+[CORE] Returns the ActivePerl build number.  This function is
+only available in the ActivePerl binary distribution.
+
+=item Win32::CopyFile(FROM, TO, OVERWRITE)
+
+[CORE] The Win32::CopyFile() function copies an existing file to a new
+file.  All file information like creation time and file attributes will
+be copied to the new file.  However it will B<not> copy the security
+information.  If the destination file already exists it will only be
+overwritten when the OVERWRITE parameter is true.  But even this will
+not overwrite a read-only file; you have to unlink() it first
+yourself.
+
+=item Win32::DomainName()
+
+[CORE] Returns the name of the Microsoft Network domain that the
+owner of the current perl process is logged into.  This function does
+B<not> work on Windows 9x.
+
+=item Win32::ExpandEnvironmentStrings(STRING)
+
+[EXT] Takes STRING and replaces all referenced environment variable
+names with their defined values.  References to environment variables
+take the form C<%VariableName%>.  Case is ignored when looking up the
+VariableName in the environment.  If the variable is not found then the
+original C<%VariableName%> text is retained.  Has the same effect
+as the following:
+
+	$string =~ s/%([^%]*)%/$ENV{$1} || "%$1%"/eg
+
+=item Win32::FormatMessage(ERRORCODE)
+
+[CORE] Converts the supplied Win32 error number (e.g. returned by
+Win32::GetLastError()) to a descriptive string.  Analogous to the
+perror() standard-C library function.  Note that C<$^E> used
+in a string context has much the same effect.
+
+	C:\> perl -e "$^E = 26; print $^E;"
+	The specified disk or diskette cannot be accessed
+
+=item Win32::FsType()
+
+[CORE] Returns the name of the filesystem of the currently active
+drive (like 'FAT' or 'NTFS').  In list context it returns three values:
+(FSTYPE, FLAGS, MAXCOMPLEN).  FSTYPE is the filesystem type as
+before.  FLAGS is a combination of values of the following table:
+
+	0x00000001  supports case-sensitive filenames
+	0x00000002  preserves the case of filenames
+	0x00000004  supports Unicode in filenames
+	0x00000008  preserves and enforces ACLs
+	0x00000010  supports file-based compression
+	0x00000020  supports disk quotas
+	0x00000040  supports sparse files
+	0x00000080  supports reparse points
+	0x00000100  supports remote storage
+	0x00008000  is a compressed volume (e.g. DoubleSpace)
+	0x00010000  supports object identifiers
+	0x00020000  supports the Encrypted File System (EFS)
+
+MAXCOMPLEN is the maximum length of a filename component (the part
+between two backslashes) on this file system.
+
+=item Win32::FreeLibrary(HANDLE)
+
+[EXT] Unloads a previously loaded dynamic-link library.  The HANDLE is
+no longer valid after this call.  See L<LoadLibrary|Win32::LoadLibrary(LIBNAME)>
+for information on dynamically loading a library.
+
+=item Win32::GetArchName()
+
+[EXT] Use of this function is deprecated.  It is equivalent with
+$ENV{PROCESSOR_ARCHITECTURE}.  This might not work on Win9X.
+
+=item Win32::GetChipName()
+
+[EXT] Returns the processor type: 386, 486 or 586 for Intel processors,
+21064 for the Alpha chip.
+
+=item Win32::GetCwd()
+
+[CORE] Returns the current active drive and directory.  This function
+does not return a UNC path, since the functionality required for such
+a feature is not available under Windows 95.
+
+=item Win32::GetFileVersion(FILENAME)
+
+[EXT] Returns the file version number from the VERSIONINFO resource of
+the executable file or DLL.  This is a tuple of four 16 bit numbers.
+In list context these four numbers will be returned.  In scalar context
+they are concatenated into a string, separated by dots.
+
+=item Win32::GetFolderPath(FOLDER [, CREATE])
+
+[EXT] Returns the full pathname of one of the Windows special folders.
+The folder will be created if it doesn't exist and the optional CREATE
+argument is true.  The following FOLDER constants are defined by the
+Win32 module, but only exported on demand:

+currently available at:
+
+http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/shell/reference/enums/csidl.asp
+
+=item Win32::GetFullPathName(FILENAME)
+
+[CORE] GetFullPathName combines the FILENAME with the current drive
+and directory name and returns a fully qualified (aka, absolute)
+path name.  In list context it returns two elements: (PATH, FILE) where
+PATH is the complete pathname component (including trailing backslash)
+and FILE is just the filename part.  Note that no attempt is made to
+convert 8.3 components in the supplied FILENAME to longnames or
+vice-versa.  Compare with Win32::GetShortPathName and
+Win32::GetLongPathName.
+
+=item Win32::GetLastError()
+
+[CORE] Returns the last error value generated by a call to a Win32 API
+function.  Note that C<$^E> used in a numeric context amounts to the
+same value.
+
+=item Win32::GetLongPathName(PATHNAME)
+
+[CORE] Returns a representation of PATHNAME composed of longname
+components (if any).  The result may not necessarily be longer
+than PATHNAME.  No attempt is made to convert PATHNAME to the
+absolute path.  Compare with Win32::GetShortPathName and
+Win32::GetFullPathName.
+
+=item Win32::GetNextAvailDrive()
+
+[CORE] Returns a string in the form of "<d>:" where <d> is the first
+available drive letter.
+
+=item Win32::GetOSVersion()
+
+[CORE] Returns the list (STRING, MAJOR, MINOR, BUILD, ID), where the
+elements are, respectively: An arbitrary descriptive string, the major
+version number of the operating system, the minor version number, the
+build number, and a digit indicating the actual operating system.
+For the ID, the values are 0 for Win32s, 1 for Windows 9X/Me and 2 for
+Windows NT/2000/XP/2003.  In scalar context it returns just the ID.
+
+Currently known values for ID MAJOR and MINOR are as follows:
+

+On Windows NT 4 SP6 and later this function returns the following
+additional values: SPMAJOR, SPMINOR, SUITEMASK, PRODUCTTYPE.
+
+SPMAJOR and SPMINOR are are the version numbers of the latest
+installed service pack.
+
+SUITEMASK is a bitfield identifying the product suites available on
+the system.  Known bits are:
+
+    VER_SUITE_SMALLBUSINESS             0x00000001
+    VER_SUITE_ENTERPRISE                0x00000002

+    VER_SUITE_TERMINAL                  0x00000010

+    VER_SUITE_EMBEDDED_RESTRICTED       0x00000800
+    VER_SUITE_SECURITY_APPLIANCE        0x00001000
+
+The VER_SUITE_xxx names are listed here to crossreference the Microsoft
+documentation.  The Win32 module does not provide symbolic names for these
+constants.
+
+PRODUCTTYPE provides additional information about the system.  It should
+be one of the following integer values:
+
+    1 - Workstation (NT 4, 2000 Pro, XP Home, XP Pro)
+    2 - Domaincontroller
+    3 - Server
+
+=item Win32::GetOSName()
+
+[EXT] In scalar context returns the name of the Win32 operating system
+being used.  In list context returns a two element list of the OS name
+and whatever edition information is known about the particular build
+(for Win9X boxes) and whatever service packs have been installed.
+The latter is roughly equivalent to the first item returned by
+GetOSVersion() in list context.
+
+Currently the possible values for the OS name are
+
+ Win32s Win95 Win98 WinMe WinNT3.51 WinNT4 Win2000 WinXP/.Net Win2003
+
+This routine is just a simple interface into GetOSVersion().  More
+specific or demanding situations should use that instead.  Another
+option would be to use POSIX::uname(), however the latter appears to
+report only the OS family name and not the specific OS.  In scalar
+context it returns just the ID.
+
+The name "WinXP/.Net" is used for historical reasons only, to maintain
+backwards compatibility of the Win32 module.  Windows .NET Server has
+been renamed as Windows 2003 Server before final release and uses a
+different major/minor version number than Windows XP.
+
+=item Win32::GetShortPathName(PATHNAME)
+
+[CORE] Returns a representation of PATHNAME that is composed of short
+(8.3) path components where available.  For path components where the
+file system has not generated the short form the returned path will
+use the long form, so this function might still for instance return a
+path containing spaces.  Compare with Win32::GetFullPathName and
+Win32::GetLongPathName.
+
+=item Win32::GetProcAddress(INSTANCE, PROCNAME)
+
+[EXT] Returns the address of a function inside a loaded library.  The
+information about what you can do with this address has been lost in
+the mist of time.  Use the Win32::API module instead of this deprecated
+function.
+
+=item Win32::GetTickCount()
+
+[CORE] Returns the number of milliseconds elapsed since the last
+system boot.  Resolution is limited to system timer ticks (about 10ms
+on WinNT and 55ms on Win9X).
+
+=item Win32::GuidGen()
+
+[EXT] Creates a globally unique 128 bit integer that can be used as a
+persistent identifier in a distributed setting. To a very high degree
+of certainty this function returns a unique value. No other
+invocation, on the same or any other system (networked or not), should
+return the same value.
+
+The return value is formatted according to OLE conventions, as groups
+of hex digits with surrounding braces.  For example:
+
+    {09531CF1-D0C7-4860-840C-1C8C8735E2AD}
+ 
+=item Win32::InitiateSystemShutdown
+
+(MACHINE, MESSAGE, TIMEOUT, FORCECLOSE, REBOOT)
+
+[EXT] Shutsdown the specified MACHINE, notifying users with the
+supplied MESSAGE, within the specified TIMEOUT interval.  Forces
+closing of all documents without prompting the user if FORCECLOSE is
+true, and reboots the machine if REBOOT is true.  This function works
+only on WinNT.
+
+=item Win32::IsAdminUser()
+
+[EXT] Returns non zero if the account in whose security context the
+current process/thread is running belongs to the local group of
+Administrators in the built-in system domain; returns 0 if not.
+Returns the undefined value and prints a warning if an error occurred.
+This function always returns 1 on Win9X.
+
+=item Win32::IsWinNT()
+
+[CORE] Returns non zero if the Win32 subsystem is Windows NT.
+
+=item Win32::IsWin95()
+
+[CORE] Returns non zero if the Win32 subsystem is Windows 95.
+
+=item Win32::LoadLibrary(LIBNAME)
+
+[EXT] Loads a dynamic link library into memory and returns its module
+handle.  This handle can be used with Win32::GetProcAddress and
+Win32::FreeLibrary.  This function is deprecated.  Use the Win32::API
+module instead.
+
+=item Win32::LoginName()
+
+[CORE] Returns the username of the owner of the current perl process.
+
+=item Win32::LookupAccountName(SYSTEM, ACCOUNT, DOMAIN, SID, SIDTYPE)
+
+[EXT] Looks up ACCOUNT on SYSTEM and returns the domain name the SID and
+the SID type.
+
+=item Win32::LookupAccountSID(SYSTEM, SID, ACCOUNT, DOMAIN, SIDTYPE)
+
+[EXT] Looks up SID on SYSTEM and returns the account name, domain name,
+and the SID type.
+
+=item Win32::MsgBox(MESSAGE [, FLAGS [, TITLE]])
+
+[EXT] Create a dialogbox containing MESSAGE.  FLAGS specifies the
+required icon and buttons according to the following table:
+
+	0 = OK
+	1 = OK and Cancel
+	2 = Abort, Retry, and Ignore
+	3 = Yes, No and Cancel
+	4 = Yes and No
+	5 = Retry and Cancel
+
+	MB_ICONSTOP          "X" in a red circle
+	MB_ICONQUESTION      question mark in a bubble
+	MB_ICONEXCLAMATION   exclamation mark in a yellow triangle
+	MB_ICONINFORMATION   "i" in a bubble
+
+TITLE specifies an optional window title.  The default is "Perl".
+
+The function returns the menu id of the selected push button:
+
+	0  Error
+
+	1  OK
+	2  Cancel
+	3  Abort
+	4  Retry
+	5  Ignore
+	6  Yes
+	7  No
+
+=item Win32::NodeName()
+
+[CORE] Returns the Microsoft Network node-name of the current machine.
+
+=item Win32::RegisterServer(LIBRARYNAME)
+
+[EXT] Loads the DLL LIBRARYNAME and calls the function DllRegisterServer.
+
+=item Win32::SetChildShowWindow(SHOWWINDOW)
+
+[CORE] Sets the I<ShowMode> of child processes started by system().
+By default system() will create a new console window for child
+processes if Perl itself is not running from a console.  Calling
+SetChildShowWindow(0) will make these new console windows invisible.
+Calling SetChildShowWindow() without arguments reverts system() to the
+default behavior.  The return value of SetChildShowWindow() is the
+previous setting or C<undef>.
+
+[EXT] The following symbolic constants for SHOWWINDOW are available
+(but not exported) from the Win32 module: SW_HIDE, SW_SHOWNORMAL,
+SW_SHOWMINIMIZED, SW_SHOWMAXIMIZED and SW_SHOWNOACTIVATE.
+
+=item Win32::SetCwd(NEWDIRECTORY)
+
+[CORE] Sets the current active drive and directory.  This function does not
+work with UNC paths, since the functionality required to required for
+such a feature is not available under Windows 95.
+
+=item Win32::SetLastError(ERROR)
+
+[CORE] Sets the value of the last error encountered to ERROR.  This is
+that value that will be returned by the Win32::GetLastError()
+function.
+
+=item Win32::Sleep(TIME)
+
+[CORE] Pauses for TIME milliseconds.  The timeslices are made available
+to other processes and threads.
+
+=item Win32::Spawn(COMMAND, ARGS, PID)
+
+[CORE] Spawns a new process using the supplied COMMAND, passing in
+arguments in the string ARGS.  The pid of the new process is stored in
+PID.  This function is deprecated.  Please use the Win32::Process module
+instead.
+
+=item Win32::UnregisterServer(LIBRARYNAME)
+
+[EXT] Loads the DLL LIBRARYNAME and calls the function
+DllUnregisterServer.
