11 Synopsis:
12 int PDC_getclipboard(char **contents, long *length);
13 int PDC_setclipboard(const char *contents, long length);
14 int PDC_freeclipboard(char *contents);
15 int PDC_clearclipboard(void);

17 Description:
18 PDC_getclipboard() gets the textual contents of the system's
19 clipboard. This function returns the contents of the clipboard
20 in the contents argument. It is the responsibilitiy of the
21 caller to free the memory returned, via PDC_freeclipboard().
22 The length of the clipboard contents is returned in the length
23 argument.
24
25 PDC_setclipboard copies the supplied text into the system's
26 clipboard, emptying the clipboard prior to the copy.
27
28 PDC_clearclipboard() clears the internal clipboard.
29
30 Return Values:
31 indicator of success/failure of call.
32 PDC_CLIP_SUCCESS the call was successful
33 PDC_CLIP_MEMORY_ERROR unable to allocate sufficient memory for
34 the clipboard contents
35 PDC_CLIP_EMPTY the clipboard contains no text
36 PDC_CLIP_ACCESS_ERROR no clipboard support
