+PDCurses for DOS
+================
+
+This directory contains PDCurses source code files specific to DOS.
+
+
+Building
+--------
+
+. Choose the appropriate makefile for your compiler:
+
+ bccdos.mak - Borland C++ 3.0+
+ gccdos.mak - DJGPP V2
+ mscdos.mak - Microsoft C
+ wccdos16.mak - Watcom 10.6+ (16-bit)
+ wccdos4g.mak - Watcom 10.6+ (32-bit)
+
+. For 16-bit compilers, you can change the memory MODEL in the makefile.
+ (Large model is the default, and recommended.)
+
+. 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 makefile
+
+ (For Watcom, use "wmake" instead of "make"; for MSVC, "nmake".) You'll
+ get the libraries (pdcurses.lib or .a, depending on your compiler; and
+ panel.lib or .a), the demos (*.exe), and a lot of object files. Note
+ that the panel library is just a copy of the main library, provided
+ for convenience; both panel and curses functions are in the main
+ library.
+
+
+Distribution Status
+-------------------
+
+The files in this directory are released to the Public Domain.
+
+
+Acknowledgements

+
+ 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 responsibilitiy 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

+ Name: pdcsetsc
+
+ Synopsis:
+ int PDC_set_blink(bool blinkon);
+ 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. Current platforms also
+ adjust the value of COLORS according to this function -- 16 for
+ FALSE, and 8 for TRUE.
+
+ 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. (Currently it only works in Win32 and X11.)
+
+ Portability X/Open BSD SYS V
