|
int PDC_getclipboard(char **contents, long *length);
|
|

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
