Example Code
This example enumerates and counts the available clipboard data formats for the clipboard opened by WinOpenClipbrd.
#define INCL_WINCLIPBOARD /* Window Clipboard Functions */
#include <os2.h>
BOOL fSuccess; /* success indicator */
HAB hab; /* anchor-block handle */
ULONG ulNext; /* next format index */
ULONG ulPrev; /* previous format index */
ULONG ulNumFormats=0; /* number of available formats */
fSuccess = WinOpenClipbrd(hab);
if (fSuccess)
{
ulPrev = 0;
/* enumerate formats and maintain count */
while ((ulNext = WinEnumClipbrdFmts(hab, ulPrev)) != 0)
{
ulNumFormats++;
ulPrev = ulNext;
}
