---------
### 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
### Portability
