+Revision history for Perl extension Win32API::File.
+
+0.10 2005-09-09
+	- Added GetFileAttributes() function and corresponding constants.
+	  (Patches from Kenneth Olwing from 2004-11-12).
+	- cygwin patches from Rafael Kitover and Reini Urban.
+	  This includes the addition of the GetFileSize(), getFileSize()
+	  setFilePointer() and GetOverlappedResult() methods and the
+	  experimental new object oriented interface.  All file position
+	  operations use either Math::BigInt objects or 8 byte integers
+	  (cygwin) for file offsets.
+
+0.0901 2005-08-30
+	- increased version number to show difference to standalone
+	  CPAN release of Win32API-File-0.09.zip
+
+0.09 2005-02-18
+        - Support 5.007+
+
+0.09 [libwin32 version only]
+	- Add AUTHOR and ABSTRACT_FROM to Makefile.PL.
+	- Trivial speed improvements.
+	- Fixed F<test.pl> if Z: is a valid drive letter.
+
+0.08 2000-04-07
+	- C<GetOsFHandle> now returns false for failure.
+	- New F<buffers.h> supports C++ compilers.
+	- Read-only output-only parameters now generate an error.
+	- Added fileLastError() since C<$^E> is often quickly overwritten.
+	- Complete rewrite of how C constants are made available in Perl.
+	- Added fileConstant(), a nice way to look-up constants at run time.
+	- Added Get/SetHandleInformation and HANDLE_FLAG_* constants.
+	- Added IOCTL_DISK_GET_MEDIA_TYPES since *_STORAGE_* fails for floppy.
+	- Added several example scripts.
+
+0.07 1999-08-17
+	- Added DeleteFile().
+	- Removed prototypes from OsFHandleOpen() and GetOsFHandle() since
+	  the C<*> doesn't prevent warnings about bareword file handles and
+	  prevents the useful usage message if no arguments given.
+	- Fixed bug due to failed C<(/k/i,/t/i)> in list context returning
+	  C<()> not C<(undef,undef)> in modern versions of Perl.
+	- Change order of C<#include>s so can build with Perl5.005 and later.
+	- Fixed C<test.pl> to ignore Perl bug where C<$^E> is truncated.
+	- Turned on C<CAPI> in C<Makefile.PL> for certain versions of Perl.
+	- Updated C<README>.
+
+0.06 1999-08-10
+	- Switch to new buffers.h and "Hungarian" notation!
+	- Added full documentation!
+	- ReadFile() no longer tries to read more bytes than asked for
+	  just because the scalar buffer can hold more bytes!
+	- createFile() does better DWIM for share mode.
+	- Return SV_NO rather than C<0> for Boolean false.
+	- For boolean args, non-empty strings are C<1>, don't convert to int.
+	- Added ":MEDIA_TYPE" export class.
+	- Added C<GENERIC_ALL> and C<GENERIC_EXECUTE> to ":GENERIC_" exports.
+	- Added C<FdGetOsFHandle()> and C<GetOsFHandle()>!
+	- Added C<OsFHandleOpenFd()> and C<OsFHandleOpen()>!
+	- Support calling C<constant()> without the useless integer argument.
+	- Auto-load/export constants with C<()> prototype so can be in-lined.
+	- Added C<IsRecognizedPartition()> and C<IsContainerPartition()>.
+	- Added C<getLogicalDrives()>.
+	- Added ":FILE_" export class for specific types of access to files.
+	- Added C<SECURITY_SQOS_PRESENT> to ":SECURITY_" export class.
+	- Added ":PARTITION_" export class for partition types.
+	- Seriously bulked up the test suite.
+
+0.05 1998-08-21
+	- "-w" no longer warns that a buffer size of "=99" "isn't numeric".
+	  nor if pass undef var for buffer size or output-only parameter.
+	- Added SetErrorMode() and :SEM_.
+	- createFile() sharing now defaults to "rw" to match C RTL.
+	- createFile() was ignoring "r" and "w" in access masks.
+
+0.04 1998-08-13
+	- Added GetLogicalDrives and GetLogicalDriveStrings.
+	- Added GetDriveType and GetVolumeInformation.
+	- Added DRIVE_* for GetDriveType().
+	- Added FS_* for GetVolumeInformation().
+	- Added createFile(), getLogicalDrives(), and attrLetsToBits() helpers.
+	- CreateFile() returns:  INVALID_HANDLE_VALUE->false, 0->"0 but true".
+	- More standardized "Hungarian" notation and uses buffers.h.
+	- Large unsigned values no longer made negative.
+
+0.03 1998-04-25
+	- Added DDD_* constants to File.pm and moved codes mistakenly
+	  exported for :DDD_ to be exported for :Misc.
+	- Split large group of constants to increase efficiency.
+	- Minor cosmetic fixes.
+
+0.02 1998-03-03
+	- Added DeviceIoControl().
+	- Added some IOCTL_STORAGE_* and IOCTL_DISK_* constants
+	- Taught test.pl to verify all exported functions and constants.
+
+0.01 1997-12-08
+	- original version; based on Win32API::Registry.
+	- release to partner

+=head1 NAME
+
+Win32API::File - Low-level access to Win32 system API calls for files/dirs.
+
+=head1 SYNOPSIS
+
+  use Win32API::File 0.08 qw( :ALL );
+
+  MoveFile( $Source, $Destination )
+    or  die "Can't move $Source to $Destination: ",fileLastError(),"\n";
+  MoveFileEx( $Source, $Destination, MOVEFILE_REPLACE_EXISTING() )
+    or  die "Can't move $Source to $Destination: ",fileLastError(),"\n";
+  [...]
+
+=head1 DESCRIPTION
+
+This provides fairly low-level access to the Win32 System API
+calls dealing with files and directories.
+
+To pass in C<NULL> as the pointer to an optional buffer, pass in
+an empty list reference, C<[]>.
+
+Beyond raw access to the API calls and related constants, this module
+handles smart buffer allocation and translation of return codes.
+
+All functions, unless otherwise noted, return a true value for success
+and a false value for failure and set C<$^E> on failure.
+
+=head2 Object Oriented/Tied Handle Interface
+
+WARNING: this is new code, use at your own risk.
+
+This version of C<Win32API::File> can be used like an C<IO::File> object:
+
+  my $file = new Win32API::File "+> foo";
+  binmode $file;
+  print $file "hello there\n";
+  seek $file, 0, 0;
+  my $line = <$file>;
+  $file->close;
+
+It also supports tying via a win32 handle (for example, from C<createFile()>):
+
+  tie FILE, 'Win32API::File', $win32_handle;
+  print FILE "...";
+
+It has not been extensively tested yet and buffered I/O is not yet implemented.
+

+
+=item C<$hObject= createFile( $sPath, $svAccess, $svShare, $rvhvOptions )>
+
+This is a Perl-friendly wrapper around C<CreateFile>.
+
+On failure, C<$hObject> gets set to a false value and C<regLastError()>
+and C<$^E> are set to the reason for the failure.  Otherwise,
+C<$hObject> gets set to a Win32 native file handle which is alwasy
+a true value [returns C<"0 but true"> in the impossible(?) case of
+the handle having a value of C<0>].
+
+C<$sPath> is the path to the file [or device, etc.] to be opened.  See
+C<CreateFile> for more information on possible special values for
+C<$sPath>.  
+
+C<$svAccess> can be a number containing the bit mask representing
+the specific type(s) of access to the file that you desire.  See the
+C<$uAccess> parameter to C<CreateFile> for more information on these
+values.
+
+More likely, C<$svAccess> is a string describing the generic type of
+access you desire and possibly the file creation options to use.  In
+this case, C<$svAccess> should contain zero or more characters from
+C<"qrw"> [access desired], zero or one character each from C<"ktn">
+and C<"ce">, and optional white space.  These letters stand for,
+respectively, "Query access", "Read access", "Write access", "Keep if
+exists", "Truncate if exists", "New file only", "Create if none", and
+"Existing file only".  Case is ignored.
+
+You can pass in C<"?"> for C<$svAccess> to have an error message
+displayed summarizing its possible values.  This is very handy when
+doing on-the-fly programming using the Perl debugger:
+
+    Win32API::File::createFile:  $svAccess can use the following:
+	One or more of the following:
+	    q -- Query access (same as 0)
+	    r -- Read access (GENERIC_READ)
+	    w -- Write access (GENERIC_WRITE)
+	At most one of the following:
+	    k -- Keep if exists
+	    t -- Truncate if exists
+	    n -- New file only (fail if file already exists)
+	At most one of the following:
+	    c -- Create if doesn't exist
+	    e -- Existing file only (fail if doesn't exist)
+      ''   is the same as 'q  k e'
+      'r'  is the same as 'r  k e'
+      'w'  is the same as 'w  t c'
+      'rw' is the same as 'rw k c'
+      'rt' or 'rn' implies 'c'.
+      Or $access can be numeric.
+
+C<$svAccess> is designed to be "do what I mean", so you can skip
+the rest of its explanation unless you are interested in the complex
+details.  Note that, if you want write access to a device, you need
+to specify C<"k"> [and perhaps C<"e">, as in C<"w ke"> or C<"rw ke">]
+since Win32 suggests C<OPEN_EXISTING> be used when opening a device.
+
+=over
+
+=item C<"q"> 
+
+Stands for "Query access".  This is really a no-op since you always have
+query access when you open a file.  You can specify C<"q"> to document
+that you plan to query the file [or device, etc.].  This is especially
+helpful when you don't want read nor write access since something like
+C<"q"> or C<"q ke"> may be easier to understand than just C<""> or C<"ke">.
+
+=item C<"r">
+
+Stands for "Read access".  Sets the C<GENERIC_READ> bit(s) in the
+C<$uAccess> that is passed to C<CreateFile>.  This is the default
+access if the C<$svAccess> parameter is missing [or if it is C<undef>
+and C<$rvhvOptions> doesn't specify an C<"Access"> option].
+
+=item C<"w">
+
+Stands for "Write access".  Sets the C<GENERIC_WRITE> bit(s) in the
+C<$uAccess> that is passed to C<CreateFile>.
+
+=item C<"k">
+
+Stands for "Keep if exists".  If the requested file exists, then it is
+opened.  This is the default unless C<GENERIC_WRITE> access has been
+requested but C<GENERIC_READ> access has not been requested.   Contrast
+with C<"t"> and C<"n">.
+
+=item C<"t">
+
+Stands for "Truncate if exists".  If the requested file exists, then
+it is truncated to zero length and then opened.  This is the default if
+C<GENERIC_WRITE> access has been requested and C<GENERIC_READ> access
+has not been requested.  Contrast with C<"k"> and C<"n">.
+
+=item C<"n">
+
+Stands for "New file only".  If the requested file exists, then it is
+not opened and the C<createFile> call fails.  Contrast with C<"k"> and
+C<"t">.  Can't be used with C<"e">.
+
+=item C<"c">
+
+Stands for "Create if none".  If the requested file does not
+exist, then it is created and then opened.  This is the default
+if C<GENERIC_WRITE> access has been requested or if C<"t"> or
+C<"n"> was specified.  Contrast with C<"e">.
+
+=item C<"e">
+
+Stands for "Existing file only".  If the requested file does not
+exist, then nothing is opened and the C<createFile> call fails.  This
+is the default unless C<GENERIC_WRITE> access has been requested or
+C<"t"> or C<"n"> was specified.   Contrast with C<"c">.   Can't be
+used with C<"n">.
+

+
+The characters from C<"ktn"> and C<"ce"> are combined to determine the

+
+C<$svShare> controls how the file is shared, that is, whether other
+processes can have read, write, and/or delete access to the file while
+we have it opened.  C<$svShare> will usually be a string containing zero
+or more characters from C<"rwd"> but can also be a numeric bit mask.
+
+C<"r"> sets the C<FILE_SHARE_READ> bit which allows other processes to have
+read access to the file.  C<"w"> sets the C<FILE_SHARE_WRITE> bit which
+allows other processes to have write access to the file.  C<"d"> sets the
+C<FILE_SHARE_DELETE> bit which allows other processes to have delete access
+to the file [ignored under Windows 95].
+
+The default for C<$svShare> is C<"rw"> which provides the same sharing as
+using regular perl C<open()>.
+
+If another process currently has read, write, and/or delete access to
+the file and you don't allow that level of sharing, then your call to
+C<createFile> will fail.  If you requested read, write, and/or delete
+access and another process already has the file open but doesn't allow
+that level of sharing, then your call to C<createFile> will fail.  Once
+you have the file open, if another process tries to open it with read,
+write, and/or delete access and you don't allow that level of sharing,
+then that process won't be allowed to open the file.
+
+C<$rvhvOptions> is a reference to a hash where any keys must be from
+the list C<qw( Access Create Share Attributes Flags Security Model )>.
+The meaning of the value depends on the key name, as described below.
+Any option values in C<$rvhvOptions> override the settings from

+=item Flags => $uFlags
+
+C<$uFlags> is an unsigned value having any of the C<FILE_FLAG_*> or
+C<FILE_ATTRIBUTE_*> bits set.  Any C<FILE_ATTRIBUTE_*> bits set via the
+C<Attributes> option are logically C<or>ed with these bits.  Defaults
+to C<0>.
+
+If opening the client side of a named pipe, then you can also specify
+C<SECURITY_SQOS_PRESENT> along with one of the other C<SECURITY_*>
+constants to specify the security quality of service to be used.
+
+=item Attributes => $sAttributes
+
+A string of zero or more characters from C<"achorst"> [see C<attrLetsToBits>
+for more information] which are converted to C<FILE_ATTRIBUTE_*> bits to
+be set in the C<$uFlags> argument passed to C<CreateFile>.
+
+=item Security => $pSecurityAttributes
+
+C<$pSecurityAttributes> should contain a C<SECURITY_ATTRIBUTES> structure
+packed into a string or C<[]> [the default].
+
+=item Model => $hModelFile
+
+C<$hModelFile> should contain a handle opened with C<GENERIC_READ>
+access to a model file from which file attributes and extended attributes
+are to be copied.  Or C<$hModelFile> can be C<0> [the default].
+
+=item Access => $sAccess
+
+=item Access => $uAccess
+
+C<$sAccess> should be a string of zero or more characters from

+"read" or C<GENERIC_READ> [the default], or "write" or
+C<GENERIC_WRITE>.
+
+C<$uAccess> should be an unsigned value containing bits set to
+indicate the type of access desired.  C<GENERIC_READ> is the default.
+
+=item Create => $sCreate
+

+return value on a poorly equipped computer would be C<("A:\\","C:\\")>.
+
+=item CloseHandle
+
+=item C<CloseHandle( $hObject )>
+
+Closes a Win32 native handle, such as one opened via C<CreateFile>.

+
+=item CopyFile
+
+=item C<CopyFile( $sOldFileName, $sNewFileName, $bFailIfExists )>
+
+C<$sOldFileName> is the path to the file to be copied. 
+C<$sNewFileName> is the path to where the file should be copied. 
+Note that you can B<NOT> just specify a path to a directory in
+C<$sNewFileName> to copy the file to that directory using the

+
+If C<$bFailIfExists> is true and C<$sNewFileName> is the path to
+a file that already exists, then C<CopyFile> will fail.  If
+C<$bFailIfExists> is falsea, then the copy of the C<$sOldFileNmae>
+file will overwrite the C<$sNewFileName> file if it already exists.

+=item CreateFile
+
+=item C<$hObject= CreateFile( $sPath, $uAccess, $uShare, $pSecAttr, $uCreate, $uFlags, $hModel )>
+
+On failure, C<$hObject> gets set to a false value and C<$^E> and
+C<fileLastError()> are set to the reason for the failure.  Otherwise,
+C<$hObject> gets set to a Win32 native file handle which is always a
+true value [returns C<"0 but true"> in the impossible(?) case of the
+handle having a value of C<0>].
+
+C<$sPath> is the path to the file [or device, etc.] to be opened.
+
+C<$sPath> can use C<"/"> or C<"\\"> as path delimiters and can even
+mix the two.  We will usually only use C<"/"> in our examples since
+using C<"\\"> is usually harder to read.
+
+Under Windows NT, C<$sPath> can start with C<"//?/"> to allow the use
+of paths longer than C<MAX_PATH> [for UNC paths, replace the leading
+C<"//"> with C<"//?/UNC/">, as in C<"//?/UNC/Server/Share/Dir/File.Ext">].
+
+C<$sPath> can start with C<"//./"> to indicate that the rest of the
+path is the name of a "DOS device."  You can use C<QueryDosDevice>
+to list all current DOS devices and can add or delete them with
+C<DefineDosDevice>.  If you get the source-code distribution of this
+module from CPAN, then it includes an example script, F<ex/ListDevs.plx>
+that will list all current DOS devices and their "native" definition.
+Again, note that this doesn't work under Win95 nor Win98.
+
+The most common such DOS devices include:

+C<DeviceIoControl> to perform miscellaneous queries and operations
+to the hard disk.   Writing raw sectors and certain other operations
+can seriously damage your files or the function of your computer.
+
+Locking this for exclusive access [by specifying C<0> for C<$uShare>]
+doesn't prevent access to the partitions on the disk nor their file

+to the partition.  Writing raw sectors and certain other operations
+can seriously damage your files or the function of your computer.
+
+Locking this for exclusive access doesn't prevent access to the
+physical drive that the partition is on so other processes can
+still access the raw sectors that way.  Locking this for exclusive

+
+Locking this for exclusive access prevents all access to the floppy.
+
+=item C<"//./PIPE/PipeName">
+
+A named pipe, created via C<CreateNamedPipe>.
+
+=back
+
+C<$uAccess> is an unsigned value with bits set indicating the
+type of access desired.  Usually either C<0> ["query" access],
+C<GENERIC_READ>, C<GENERIC_WRITE>, C<GENERIC_READ|GENERIC_WRITE>,
+or C<GENERIC_ALL>.  More specific types of access can be specified,
+such as C<FILE_APPEND_DATA> or C<FILE_READ_EA>.
+
+C<$uShare> controls how the file is shared, that is, whether other
+processes can have read, write, and/or delete access to the file while
+we have it opened.  C<$uShare> is an unsigned value with zero or more
+of these bits set:  C<FILE_SHARE_READ>, C<FILE_SHARE_WRITE>, and
+C<FILE_SHARE_DELETE>.
+
+If another process currently has read, write, and/or delete access to
+the file and you don't allow that level of sharing, then your call to
+C<CreateFile> will fail.  If you requested read, write, and/or delete
+access and another process already has the file open but doesn't allow
+that level of sharing, thenn your call to C<createFile> will fail.  Once
+you have the file open, if another process tries to open it with read,
+write, and/or delete access and you don't allow that level of sharing,
+then that process won't be allowed to open the file.
+
+C<$pSecAttr> should either be C<[]> [for C<NULL>] or a
+C<SECURITY_ATTRIBUTES> data structure packed into a string.
+For example, if C<$pSecDesc> contains a C<SECURITY_DESCRIPTOR>
+structure packed into a string, perhaps via:
+
+    RegGetKeySecurity( $key, 4, $pSecDesc, 1024 );
+
+then you can set C<$pSecAttr> via:
+
+    $pSecAttr= pack( "L P i", 12, $pSecDesc, $bInheritHandle );
+
+C<$uCreate> is one of the following values:  C<OPEN_ALWAYS>,
+C<OPEN_EXISTING>, C<TRUNCATE_EXISTING>, C<CREATE_ALWAYS>, and
+C<CREATE_NEW>.
+
+C<$uFlags> is an unsigned value with zero or more bits set indicating
+attributes to associate with the file [C<FILE_ATTRIBUTE_*> values] or
+special options [C<FILE_FLAG_*> values].
+
+If opening the client side of a named pipe, then you can also set
+C<$uFlags> to include C<SECURITY_SQOS_PRESENT> along with one of the
+other C<SECURITY_*> constants to specify the security quality of
+service to be used.
+
+C<$hModel> is C<0> [or C<[]>, both of which mean C<NULL>] or a Win32
+native handle opened with C<GENERIC_READ> access to a model file from
+which file attributes and extended attributes are to be copied if a
+new file gets created.
+
+Examples:
+
+    $hFlop= CreateFile( "//./A:", GENERIC_READ(),
+      FILE_SHARE_READ(), [], OPEN_EXISTING(), 0, [] )
+      or  die "Can't prevent others from writing to floppy: $^E\n";

+=item DefineDosDevice
+
+=item C<DefineDosDevice( $uFlags, $sDosDeviceName, $sTargetPath )>
+
+Defines a new DOS device, overrides the current definition of a DOS
+device, or deletes a definition of a DOS device.  Like most routines,
+returns a true value if successful and a false value [and sets C<$^E>
+and C<regLastError()>] on failure.
+
+C<$sDosDeviceName> is the name of a DOS device for which we'd like
+to add or delete a definition.
+
+C<$uFlags> is an unsigned value with zero or more of the following
+bits set:
+
+=over
+
+=item C<DDD_RAW_TARGET_PATH>
+
+Indicates that C<$sTargetPath> will be a raw Windows NT object name. 
+This usually means that C<$sTargetPath> starts with C<"\\Device\\">. 
+Note that you cannot use C<"/"> in place of C<"\\"> in raw target path
+names.
+
+=item C<DDD_REMOVE_DEFINITION>
+
+Requests that a definition be deleted.  If C<$sTargetPath> is
+C<[]> [for C<NULL>], then the most recently added definition for
+C<$sDosDeviceName> is removed.  Otherwise the most recently added
+definition matching C<$sTargetPath> is removed.
+
+If the last definition is removed, then the DOS device name is
+also deleted.
+
+=item C<DDD_EXACT_MATCH_ON_REMOVE>
+
+When deleting a definition, this bit causes each C<$sTargetPath> to
+be compared to the full-length definition when searching for the most
+recently added match.  If this bit is not set, then C<$sTargetPath>
+only needs to match a prefix of the definition.
+
+=back
+
+C<$sTargetPath> is the DOS device's specific definition that you
+wish to add or delete.  For C<DDD_RAW_TARGET_PATH>, these usually
+start with C<"\\Device\\">.  If the C<DDD_RAW_TARGET_PATH> bit is
+not set, then C<$sTargetPath> is just an ordinary path to some file
+or directory, providing the functionality of the B<subst> command.
+
+=item DeleteFile
+
+=item C<DeleteFile( $sFileName )>
+
+Deletes the named file.  Compared to Perl's C<unlink>, C<DeleteFile>
+has the advantage of not deleting read-only files.  For B<some>
+versions of Perl, C<unlink> silently calls C<chmod> whether it needs
+to or not before deleting the file so that files that you have
+protected by marking them as read-only are not always protected from
+Perl's C<unlink>.
+
+Like most routines, returns a true value if successful and a false
+value [and sets C<$^E> and C<regLastError()>] on failure.
+
+=item DeviceIoControl
+
+=item C<DeviceIoControl( $hDevice, $uIoControlCode, $pInBuf, $lInBuf, $opOutBuf, $lOutBuf, $olRetBytes, $pOverlapped )>
+
+Requests a special operation on an I/O [input/output] device, such
+as ejecting a tape or formatting a disk.  Like most routines, returns
+a true value if successful and a false value [and sets C<$^E> and
+C<regLastError()>] on failure.
+
+C<$hDevice> is a Win32 native file handle to a device [return value
+from C<CreateFile>].
+
+C<$uIoControlCode> is an unsigned value [a C<IOCTL_*> or C<FSCTL_*>
+constant] indicating the type query or other operation to be performed.
+
+C<$pInBuf> is C<[]> [for C<NULL>] or a data structure packed into a
+string.  The type of data structure depends on the C<$uIoControlCode>
+value.  C<$lInBuf> is C<0> or the length of the structure in
+C<$pInBuf>.  If C<$pInBuf> is not C<[]> and C<$lInBuf> is C<0>, then
+C<$lInBuf> will automatically be set to C<length($pInBuf)> for you.
+
+C<$opOutBuf> is C<[]> [for C<NULL>] or will be set to contain a
+returned data structure packed into a string.  C<$lOutBuf> indicates
+how much space to allocate in C<$opOutBuf> for C<DeviceIoControl> to
+store the data structure.  If C<$lOutBuf> is a number and C<$opOutBuf>
+already has a buffer allocated for it that is larger than C<$lOutBuf>
+bytes, then this larger buffer size will be passed to C<DeviceIoControl>.
+However, you can force a specific buffer size to be passed to
+C<DeviceIoControl> by prepending a C<"="> to the front of C<$lOutBuf>.
+
+C<$olRetBytes> is C<[]> or is a scalar to receive the number of bytes
+written to C<$opOutBuf>.  Even when C<$olRetBytes> is C<[]>, a valid
+pointer to a C<DWORD> [and not C<NULL>] is passed to C<DeviceIoControl>.
+In this case, C<[]> just means that you don't care about the value
+that might be written to C<$olRetBytes>, which is usually the case
+since you can usually use C<length($opOutBuf)> instead.
+
+C<$pOverlapped> is C<[]> or is a C<OVERLAPPED> structure packed into
+a string.  This is only useful if C<$hDevice> was opened with the
+C<FILE_FLAG_OVERLAPPED> flag set.
+
+=item FdGetOsFHandle
+
+=item C<$hNativeHandle= FdGetOsFHandle( $ivFd )>
+
+C<FdGetOsFHandle> simply calls C<_get_osfhandle()>.  It was renamed
+to better fit in with the rest the function names of this module,
+in particular to distinguish it from C<GetOsFHandle>.  It takes an
+integer file descriptor [as from Perl's C<fileno>] and returns the
+Win32 native file handle associated with that file descriptor or
+C<INVALID_HANDLE_VALUE> if C<$ivFd> is not an open file descriptor.
+
+When you call Perl's C<open> to set a Perl file handle [like C<STDOUT>],
+Perl calls C's C<fopen> to set a stdio C<FILE *>.  C's C<fopen> calls
+something like Unix's C<open>, that is, Win32's C<_sopen>, to get an
+integer file descriptor [where 0 is for C<STDIN>, 1 for C<STDOUT>, etc.].
+Win32's C<_sopen> calls C<CreateFile> to set a C<HANDLE>, a Win32 native
+file handle.  So every Perl file handle [like C<STDOUT>] has an integer
+file descriptor associated with it that you can get via C<fileno>.  And,
+under Win32, every file descriptor has a Win32 native file handle
+associated with it.  C<FdGetOsFHandle> lets you get access to that.
+
+C<$hNativeHandle> is set to C<INVALID_HANDLE_VALUE> [and
+C<lastFileError()> and C<$^E> are set] if C<FdGetOsFHandle> fails. 
+See also C<GetOsFHandle> which provides a friendlier interface.
+
+=item fileConstant
+
+=item C<$value= fileConstant( $sConstantName )>
+
+Fetch the value of a constant.  Returns C<undef> if C<$sConstantName>
+is not the name of a constant supported by this module.  Never sets
+C<$!> nor C<$^E>.
+
+This function is rarely used since you will usually get the value of a
+constant by having that constant imported into your package by listing
+the constant name in the C<use Win32API::File> statement and then
+simply using the constant name in your code [perhaps followed by
+C<()>].  This function is useful for verifying constant names not in
+Perl code, for example, after prompting a user to type in a constant
+name.
+
+=item fileLastError
+
+=item C<$svError= fileLastError();>
+
+=item C<fileLastError( $uError );>
+
+Returns the last error encountered by a routine from this module. 
+It is just like C<$^E> except it isn't changed by anything except
+routines from this module.  Ideally you could just use C<$^E>, but
+current versions of Perl often overwrite C<$^E> before you get a
+chance to check it and really old versions of Perl don't really
+support C<$^E> under Win32.
+
+Just like C<$^E>, in a numeric context C<fileLastError()> returns
+the numeric error value while in a string context it returns a
+text description of the error [actually it returns a Perl scalar
+that contains both values so C<$x= fileLastError()> causes C<$x>
+to give different values in string vs. numeric contexts].
+
+The last form sets the error returned by future calls to
+C<fileLastError()> and should not be used often.  C<$uError> must
+be a numeric error code.  Also returns the dual-valued version
+of C<$uError>.
+
+=item GetDriveType
+
+=item C<$uDriveType= GetDriveType( $sRootPath )>
+
+Takes a string giving the path to the root directory of a file system

+
+The file or directory is an archive file or directory. Applications use
+this attribute to mark files for backup or removal.
+
+=item C<FILE_ATTRIBUTE_COMPRESSED>
+
+The file or directory is compressed. For a file, this means that all of

+
+Reserved; do not use. 
+
+=item C<FILE_ATTRIBUTE_DIRECTORY>
+
+The handle identifies a directory.

+encryption is the default for newly created files and subdirectories. 
+
+=item C<FILE_ATTRIBUTE_HIDDEN>
+
+The file or directory is hidden. It is not included in an ordinary directory
+listing. 
+
+=item C<FILE_ATTRIBUTE_NORMAL>
+
+The file or directory has no other attributes set. This attribute is valid
+only if used alone. 
+
+=item C<FILE_ATTRIBUTE_NOT_CONTENT_INDEXED>
+
+The file will not be indexed by the content indexing service. 
+
+=item C<FILE_ATTRIBUTE_OFFLINE>
+
+The data of the file is not immediately available. This attribute indicates
+that the file data has been physically moved to offline storage. This
+attribute is used by Remote Storage, the hierarchical storage management
+software. Applications should not arbitrarily change this attribute. 
+
+=item C<FILE_ATTRIBUTE_READONLY>
+
+The file or directory is read-only. Applications can read the file but cannot
+write to it or delete it. In the case of a directory, applications cannot

+=item C<FILE_ATTRIBUTE_SYSTEM>
+
+The file or directory is part of, or is used exclusively by, the operating
+system. 
+
+=item C<FILE_ATTRIBUTE_TEMPORARY>
+
+The file is being used for temporary storage. File systems avoid writing
+data back to mass storage if sufficient cache memory is available, because
+often the application deletes the temporary file shortly after the handle is
+closed. In that case, the system can entirely avoid writing the data.
+Otherwise, the data will be written after the handle is closed.

+C<fileLastError()> and C<$^E>.
+
+C<$sRootPath> is a string specifying the path to the root of the file system,

+
+C<$osVolName> is a scalar to be set to the string representing the

+=item C<FS_CASE_IS_PRESERVED>
+
+The file system preserves the case of file names [usually true].
+That is, it doesn't change the case of file names such as forcing

+
+=item C<FS_CASE_SENSITIVE>
+
+The file system supports the ability to not ignore the case of file
+names [but might ignore case the way you are using it].  That is, the
+file system has the ability to force you to get the letter case of a

+=item C<MoveFile( $sOldName, $sNewName )>
+
+Renames a file or directory.  C<$sOldName> is the name of the existing

+to give the file or directory.  Returns a true value if the move
+succeeds.  For failure, returns a false value and sets
+C<fileLastErorr()> and C<$^E> to the reason for the failure.
+
+Files can be "renamed" between file systems and the file contents and
+some attributes will be moved.  Directories can only be renamed within
+one file system.  If there is already a file or directory named
+C<$sNewName>, then C<MoveFile> will fail.

+
+Renames a file or directory.  C<$sOldName> is the name of the existing

+
+If this bit is set and a file [but not a directory] named C<$sNewName>

+
+Allows files [but not directories] to be moved between file systems
+by copying the C<$sOldName> file data and some attributes to
+C<$sNewName> and then deleting C<$sOldName>.  If this bit is not set

+
+Preliminary verifications are made and then an entry is added to the

+next time this copy of the operating system is booted [right after
+any automatic file system checks have completed].  This is not
+supported under Windows 95.
+
+When this bit is set, C<$sNewName> can be C<[]> [for C<NULL>] to
+indicate that C<$sOldName> should be deleted during the next boot
+rather than renamed.
+
+Setting both the C<MOVEFILE_COPY_ALLOWED> and
+C<MOVEFILE_DELAY_UNTIL_REBOOT> bits will cause C<MoveFileEx> to fail.
+
+=item C<MOVEFILE_WRITE_THROUGH>
+
+Ensures that C<MoveFileEx> won't return until the operation has
+finished and been flushed to disk.   This is not supported under

+=item C<OsFHandleOpen( FILE, $hNativeHandle, $sMode )>
+
+Opens a Perl file handle based on an already open Win32 native

+Returns a true value if the open operation succeeded.  For failure,
+returns a false value and sets C<$!> [and possibly C<fileLastError()>
+and C<$^E>] to the reason for the failure.
+
+C<FILE> is a Perl file handle [in any of the supported forms, a
+bareword, a string, a typeglob, or a reference to a typeglob] that
+will be opened.  If C<FILE> is already open, it will automatically
+be closed before it is reopened.
+
+C<$hNativeHandle> is an open Win32 native file handle, probably the
+return value from C<CreateFile> or C<createFile>.
+
+C<$sMode> is string of zero or more letters from C<"rwatb">.  These
+are translated into a combination C<O_RDONLY> [C<"r">], C<O_WRONLY>
+[C<"w">], C<O_RDWR> [C<"rw">], C<O_APPEND> [C<"a">], C<O_TEXT>
+[C<"t">], and C<O_BINARY> [C<"b">] flags [see the L<Fcntl> module]
+that is passed to C<OsFHandleOpenFd>.   Currently only C<O_APPEND>
+and C<O_TEXT> have any significance.
+
+Also, a C<"r"> and/or C<"w"> in C<$sMode> is used to decide how the
+file descriptor is converted into a Perl file handle, even though this
+doesn't appear to make a difference.  One of the following is used:
+
+    open( FILE, "<&=".$ivFd )	# "r" w/o "w"
+    open( FILE, ">&=".$ivFd )	# "w" w/o "r"
+    open( FILE, "+<&=".$ivFd )	# both "r" and "w"
+
+C<OsFHandleOpen> eventually calls the Win32-specific C routine
+C<_open_osfhandle()> or Perl's "improved" version called
+C<win32_open_osfhandle()>.  Prior to Perl5.005, C's
+C<_open_osfhandle()> is called which will fail if
+C<GetFileType($hNativeHandle)> would return C<FILE_TYPE_UNKNOWN>.  For
+Perl5.005 and later, C<OsFHandleOpen> calls C<win32_open_osfhandle()>
+from the Perl DLL which doesn't have this restriction.
+
+=item OsFHandleOpenFd
+
+=item C<$ivFD= OsFHandleOpenFd( $hNativeHandle, $uMode )>
+
+Opens a file descriptor [C<$ivFD>] based on an already open Win32

+Win32-specific C routine C<_open_osfhandle()> or Perl's "improved"
+version called C<win32_open_osfhandle()>.  Prior to Perl5.005 and in Cygwin
+Perl, C's C<_open_osfhandle()> is called which will fail if

+exported by the C<Fcntl> module.  Currently only C<O_APPEND> and
+C<O_TEXT> have any significance.
+
+C<$ivFD> will be non-negative if the open operation was successful.

+
+=item QueryDosDevice
+
+=item C<$olTargetLen= QueryDosDevice( $sDosDeviceName, $osTargetPath, $lTargetBuf )>
+
+Looks up the definition of a given "DOS" device name, yielding the
+active Windows NT native device name along with any currently dormant
+definitions.
+
+C<$sDosDeviceName> is the name of the "DOS" device whose definitions
+we want.  For example, C<"C:">, C<"COM1">, or C<"PhysicalDrive0">.
+If C<$sDosDeviceName> is C<[]> [for C<NULL>], the list of all DOS
+device names is returned instead.
+
+C<$osTargetPath> will be assigned a string containing the list of
+definitions.  The definitions are each C<'\0'>-terminate and are
+concatenated into the string, most recent first, with an extra C<'\0'>
+at the end of the whole string [see C<GetLogicalDriveStrings> for
+a sample of this format].
+
+C<$lTargetBuf> is the size [in bytes] of the buffer to allocate for
+C<$osTargetPath>.  See L<Buffer Sizes> for more information.
+
+C<$olTargetLen> is set to the number of bytes written to
+C<$osTargetPath> but you can also use C<length($osTargetPath)>
+to determine this.
+
+For failure, C<0> is returned and C<fileLastError()> and C<$^E> are
+set to the reason for the failure.
+
+=item ReadFile
+
+=item C<ReadFile( $hFile, $opBuffer, $lBytes, $olBytesRead, $pOverlapped )>
+
+Reads bytes from a file or file-like device.  Returns a true value if
+the read operation was successful.  For failure, returns a false value
+and sets C<fileLastError()> and C<$^E> for the reason for the failure.
+
+C<$hFile> is a Win32 native file handle that is already open to the
+file or device to read from.
+
+C<$opBuffer> will be set to a string containing the bytes read.
+
+C<$lBytes> is the number of bytes you would like to read. 
+C<$opBuffer> is automatically initialized to have a buffer large
+enough to hold that many bytes.  Unlike other buffer sizes, C<$lBytes>
+does not need to have a C<"="> prepended to it to prevent a larger
+value to be passed to the underlying Win32 C<ReadFile> API.  However,
+a leading C<"="> will be silently ignored, even if Perl warnings are
+enabled.
+
+If C<$olBytesRead> is not C<[]>, it will be set to the actual number
+of bytes read, though C<length($opBuffer)> can also be used to
+determine this.
+
+C<$pOverlapped> is C<[]> or is a C<OVERLAPPED> structure packed
+into a string.  This is only useful if C<$hFile> was opened with
+the C<FILE_FLAG_OVERLAPPED> flag set.

+=item SetErrorMode
+
+=item C<$uOldMode= SetErrorMode( $uNewMode )>
+
+Sets the mode controlling system error handling B<and> returns the

+zero or more of the following bits set:
+
+=over
+
+=item C<SEM_FAILCRITICALERRORS>
+
+If set, indicates that when a critical error is encountered, the call
+that triggered the error fails immediately.  Normally this bit is not
+set, which means that a critical error causes a dialogue box to appear
+notifying the desktop user that some application has triggered a
+critical error.   The dialogue box allows the desktop user to decide
+whether the critical error is returned to the process, is ignored, or
+the offending operation is retried.
+
+This affects the C<CreateFile> and C<GetVolumeInformation> calls.
+
+Setting this bit is useful for allowing you to check whether a floppy
+diskette is in the floppy drive.
+
+=item C<SEM_NOALIGNMENTFAULTEXCEPT>
+
+If set, this causes memory access misalignment faults to be
+automatically fixed in a manner invisible to the process.  This flag
+is ignored on x86-based versions of Windows NT.  This flag is not
+supported on Windows 95.
+
+=item C<SEM_NOGPFAULTERRORBOX>
+
+If set, general protection faults do not generate a dialogue box but
+can instead be handled by the process via an exception handler.  This
+bit should not be set by programs that don't know how to handle such
+faults.
+
+=item C<SEM_NOOPENFILEERRORBOX>
+
+If set, then when an attempt to continue reading from or writing to
+an already open file [usually on a removable medium like a floppy
+diskette] finds the file no longer available, the call will
+immediately fail.  Normally this bit is not set, which means that
+instead a dialogue box will appear notifying the desktop user that
+some application has run into this problem.   The dialogue box allows
+the desktop user to decide whether the failure is returned to the
+process, is ignored, or the offending operation is retried.

+=item setFilePointer
+
+=item C<$uNewPos = setFilePointer( $hFile, $ivOffset, $uFromWhere )>
+
+This is a perl-friendly wrapper for the SetFilePointer API (below).
+C<$ivOffset> can be a 64 bit integer or C<Math::BigInt> object if your Perl
+doesn't have 64 bit integers. The return value is the new offset and will
+likewise be a 64 bit integer or a C<Math::BigInt> object.
+
+=item SetFilePointer
+
+=item C<$uNewPos = SetFilePointer( $hFile, $ivOffset, $ioivOffsetHigh, $uFromWhere )>
+
+The native Win32 version of C<seek()>.  C<SetFilePointer> sets the
+position within a file where the next read or write operation will
+start from.
+
+C<$hFile> is a Win32 native file handle.
+
+C<$uFromWhere> is either C<FILE_BEGIN>, C<FILE_CURRENT>, or
+C<FILE_END>, indicating that the new file position is being specified
+relative to the beginning of the file, the current file pointer, or
+the end of the file, respectively.
+
+C<$ivOffset> is [if C<$ioivOffsetHigh> is C<[]>] the offset [in bytes]
+to the new file position from the position specified via
+C<$uFromWhere>.  If C<$ioivOffsetHigh> is not C<[]>, then C<$ivOffset>
+is converted to an unsigned value to be used as the low-order 4 bytes
+of the offset.
+
+C<$ioivOffsetHigh> can be C<[]> [for C<NULL>] to indicate that you are
+only specifying a 4-byte offset and the resulting file position will
+be 0xFFFFFFFE or less [just under 4GB].  Otherwise C<$ioivOfffsetHigh>
+starts out with the high-order 4 bytes [signed] of the offset and gets
+set to the [unsigned] high-order 4 bytes of the resulting file position.
+
+The underlying C<SetFilePointer> returns C<0xFFFFFFFF> to indicate
+failure, but if C<$ioivOffsetHigh> is not C<[]>, you would also have
+to check C<$^E> to determine whether C<0xFFFFFFFF> indicates an error
+or not.  C<Win32API::File::SetFilePointer> does this checking for you
+and returns a false value if and only if the underlying
+C<SetFilePointer> failed.  For this reason, C<$uNewPos> is set to
+C<"0 but true"> if you set the file pointer to the beginning of the
+file [or any position with 0 for the low-order 4 bytes].
+
+So the return value will be true if the seek operation was successful.
+For failure, a false value is returned and C<fileLastError()> and
+C<$^E> are set to the reason for the failure.

+=item SetHandleInformation
+
+=item C<SetHandleInformation( $hObject, $uMask, $uFlags )>
+
+Sets the flags associated with a Win32 native file handle or object
+handle.  Returns a true value if the operation was successful.  For
+failure, returns a false value and sets C<fileLastError()> and C<$^E>
+for the reason for the failure.
+
+C<$hObject> is an open Win32 native file handle or an open Win32 native
+handle to some other type of object.
+
+C<$uMask> is an unsigned value having one or more of the bits
+C<HANDLE_FLAG_INHERIT> and C<HANDLE_FLAG_PROTECT_FROM_CLOSE> set.
+Only bits set in C<$uMask> will be modified by C<SetHandleInformation>.
+
+C<$uFlags> is an unsigned value having zero or more of the bits
+C<HANDLE_FLAG_INHERIT> and C<HANDLE_FLAG_PROTECT_FROM_CLOSE> set.
+For each bit set in C<$uMask>, the cooresponding bit in the handle's
+flags is set to the value of the cooresponding bit in C<$uFlags>.
+
+If C<$uOldFlags> were the value of the handle's flags before the
+call to C<SetHandleInformation>, then the value of the handle's
+flags afterward would be:
+
+    ( $uOldFlags & ~$uMask ) | ( $uFlags & $uMask )
+
+[at least as far as the C<HANDLE_FLAG_INHERIT> and

+=item WriteFile

+sets C<fileLastError()> and C<$^E> for the reason for the failure.
+
+C<$hFile> is a Win32 native file handle that is already open to the

+
+C<$pBuffer> is a string containing the bytes to be written.

+ */
+
+/* Buffer arguments are usually followed by an argument (or two) specifying
+ * their size and/or returning the size of data written.  The size can be
+ * measured in bytes ["lSize"] or in characters [for (char *) buffers such as
+ * for *A() routines, these sizes are also called "lSize", but are called
+ * "lwSize" for (WCHAR *) buffers, UNICODE strings, such as for *W() routines].
+ *
+ * Before calling the actual C function, you must make sure the Perl variable
+ * actually has a big enough buffer allocated, and, if the user didn't want
+ * to specify a buffer size, set the buffer size to be correct.  This is what
+ * the grow_*() macros are for.  They also handle special meanings of the
+ * buffer size argument [described below].
+ *
+ * Once the actual C function returns, you must set the Perl variable to know
+ * the size of the written data.  This is what the trunc_*() macros are for.
+ *
+ * The size sometimes does and sometimes doesn't include the trailing '\0'
+ * [or L'\0'], so we always add or substract 1 in the appropriate places so
+ * we don't care about this detail.
+ *
+ * A call may  1) request a pointer to the buffer size which means that
+ * the buffer size will be overwritten with the size of the data written;
+ * 2) have an extra argument which is a pointer to the place to write the
+ * size of the written data;  3) provide the size of the written data in
+ * the function's return value;  4) format the data so that the length
+ * can be determined by examining the data [such as with '\0'-terminated
+ * strings];  or  5) write fixed-length data [usually sizeof(STRUCT)].
+ * This obviously determines what you should use in the trunc_*() macro
+ # to specify the size of the output value.
+ *
+ * The user can pass in an empty list reference, C<[]>, to indicate C<NULL>
+ * for the pointer to the buffer which means that they don't want that data.
+ *
+ * The user can pass in C<[]> or C<0> to indicate that they don't care about
+ * the buffer size [we aren't programming in C here, after all] and just try
+ * to get the data.  This will work if either the buffer already alloated for
+ * the SV [scalar value] is large enough to hold the data or the API provides
+ * an easy way to determine the required size [and the XS code uses it].
+ *
+ * If the user passes in a numeric value for a buffer size, then the XS
+ * code makes sure that the buffer is at least large enough to hold a value
+ * of that size and then passes in how large the buffer is.  So the buffer
+ * size passed to the API call is the larger of the size requested by the
+ * user and the size of the buffer aleady allocated to the SV.
+ *
+ * The user can also pass in a string consisting of a leading "=" followed
+ * by digits for a buffer size.  This means just use the size specified after
+ * the equals sign, even if the allocated buffer is larger.  The XS code will
+ * still allocate a large enough buffer before the first call.
+ *
+ * If the function is nice enough to tell us that a buffer was too small
+ * [usually via ERROR_MORE_DATA] _and_ how large the buffer needs to be,
+ * then the XS code should enlarge the buffer(s) and repeat the call [once].
+ * This resizing is _not_ done for buffers whose size was specified with a
+ * leading "=".
+ *
+ * Only grow_buf() and perhaps trunc_buf() can be used in a typemap file.
+ * The other macros would be used in the parameter declarations or INPUT:
+ * section [grow_*()], the INIT: section [init_*()], or the OUTPUT: section
+ * [trunc_*()].
+ *
+ * Buffer arguments should be initialied with C<= NO_INIT> [or C<= NULL;>].
+ *
+ * See also the F<typemap> file.  C<oDWORD>, for example, is for an output-
+ * only parameter of type C<DWORD> and you should simply C<#define> it to be
+ * C<DWORD>.  In F<typemap>, C<oDWORD> is treated differently than C<DWORD>
+ * in two ways.
+ *
+ * First, if C<undef> is passed in, a C<DWORD> could generate a warning
+ * when it gets converted to 0 while C<oDWORD> will never generate such a
+ * warning for C<undef>.  This first difference doesn't apply if specific
+ * initialization is specified for the variable, as in C<= init_buf_l($var);>.
+ * In particular, the init_*() macros also convert C<undef> to 0 without
+ * ever producing a warning.
+ *
+ * Second, passing in a read-only SV for a C<oDWORD> parameter will generate
+ * a fatal error on output when we try to update the SV.  For C<DWORD>, we
+ * won't update a read-only SV since passing in a literal constant for a
+ * buffer size is a useful thing to do even though it prevents us from
+ * returning the size of data written via that SV.  Since we should use a
+ * trunc_*() macro to output the actual data, the user should be able to
+ * determine the size of data written based on the size of the scalar we
+ * output anyway.
+ *
+ * This second difference doesn't apply unless the paremter is listed in
+ * the OUTPUT: section without specific output instructions.  We define
+ * no macros for outputing buffer length parameters so be careful to use
+ * C<oDWORD> [for example] for them if and only if they are output-only.
+ *
+ * Note that C<oDWORD> is the same as C<DWORD> in that, if a defined value
+ * is passed in, it is used [and can generate a warning if the value is
+ * "not numeric"].  So although C<oDWORD> is for output-only parameters,
+ * we still initialize the C variable before calling the API.  This is good
+ * in case the parameter isn't always strictly output-only due to upgrades,
+ * bugs, etc.
+ *
+ * Here is a made-up example that shows several cases:
+ *
+ * # Actual GetDataW() returns length of data written to ioswName, not bool.
+ * bool
+ * GetDataW( ioswName, ilwName, oswText, iolwText, opJunk, opRec, ilRec, olRec )
+ *	WCHAR *	ioswName	= NO_INIT
+ *	DWORD	ilwName		= NO_INIT
+ *	WCHAR *	oswText		= NO_INIT
+ *	DWORD	&iolwText	= init_buf_l($arg);
+ *	void *	opJunk		= NO_INIT
+ *	BYTE *	opRec		= NO_INIT
+ *	DWORD	ilRec		= init_buf_l($arg);
+ *	oDWORD	&olRec
+ * PREINIT:
+ *	DWORD	olwName;
+ * INIT:
+ *	grow_buf_lw( ioswName,ST(0), ilwName,ST(1) );
+ *	grow_buf_lw( oswText,ST(2), iolwText,ST(3) );
+ *	grow_buf_typ( opJunk,ST(4),void *, LONG_STRUCT_TYPEDEF );
+ *	grow_buf_l( opRec,ST(5),BYTE *, ilRec,ST(6) );
+ * CODE:
+ *	olwName= GetDataW( ioswName, ilwName, oswText, &iolwText,
+ *			   (LONG_STRUCT_TYPEDEF *)opJunk, opRec, &iolRec );
+ *	if(  0 == olwName  &&  ERROR_MORE_DATA == GetLastError()
+ *	 &&  ( autosize(ST(1)) || autosize(ST(3)) || autosize(ST(6)) )  ) {
+ *	    if(  autosize(ST(1))  )
+ *		grow_buf_lw( ioswName,ST(0), ilwName,ST(1) );
+ *	    if(  autosize(ST(3))  )
+ *		grow_buf_lw( oswText,ST(2), iolwText,ST(3) );
+ *	    if(  autosize(ST(6))  )
+ *		grow_buf_l( opRec,ST(5),BYTE *, iolRec,ST(6) );
+ *	    olwName= GetDataW( ioswName, ilwName, oswText, &iolwText,
+ *			       (LONG_STRUCT_TYPEDEF *)opJunk, opRec, &iolRec );
+ *	}
+ *	RETVAL=  0 != olwName;
+ * OUTPUT:
+ *	RETVAL
+ *	ioswName	trunc_buf_lw( RETVAL, ioswName,ST(0), olwName );
+ *	oswText		trunc_buf_lw( RETVAL, oswText,ST(2), iolwText );
+ *	iolwText
+ *	opJunk		trunc_buf_typ(RETVAL,opJunk,ST(4),LONG_STRUCT_TYPEDEF);
+ *	opRec		trunc_buf_l( RETVAL, opRec,ST(5), olRec );
+ *	olRec
+ *
+ * The above example would be more complex and less efficient if we used
+ * C<DWORD * iolwText> in place of C<DWORD  &iolwText>.  The only possible
+ * advantage would be that C<NULL> would be passed in for C<iolwText> if
+ * _both_ C<$oswText> and C<$iolwText> were specified as C<[]>.  The *_pl*()
+ * macros are defined [and C<DWORD *> specified in F<typemap>] so we can
+ * handle those cases but it is usually better to use the *_l*() macros
+ * instead by specifying C<&> instead of C<*>.  Using C<&> instead of C<*>
+ * is usually better when dealing with scalars, even if they aren't buffer
+ * sizes.  But you must use C<*> if it is important for that parameter to
+ * be able to pass C<NULL> to the underlying API.
+ *
+ * In Win32API::, we try to use C<*> for buffer sizes of optional buffers
+ * and C<&> for buffer sizes of required buffers.
+ *
+ * For parameters that are pointers to things other than buffers or buffer
+ * sizes, we use C<*> for "important" parameters [so that using C<[]>
+ * generates an error rather than fetching the value and just throwing it
+ * away], and for optional parameters [in case specifying C<NULL> is or
+ * becomes important].  Otherwise we use C<&> [for "unimportant" but
+ * required parameters] so the user can specify C<[]> if they don't care
+ * about it.  The output handle of an "open" routine is "important".
