This example empties the clipboard (opened by WinOpenClipbrd), removing and freeing all handles to data in the clipboard.

#define INCL_WINCLIPBOARD       /* Window Clipboard Functions   */
#include <os2.h>

BOOL  fSuccess;         /* success indicator                    */
HAB   hab;              /* anchor-block handle                  */


fSuccess = WinOpenClipbrd(hab);

if (fSuccess)
   fSuccess = WinEmptyClipbrd(hab);
