+---------
+
+### 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
+
+    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
