+  Name:                                                         clipboard
+
+  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
