This function obtains a handle to the current clipboard data with a specified format.

Syntax

WinQueryClipbrdData(hab, fmt)

Parameters

hab (HAB) - input
Anchor-block handle.
fmt (ULONG) - input
Format of the data to be accessed.
In addition to the predefined formats, private formats can be created using the standard system atom manager. The following is the list of standard clipboard formats:
CF_TEXT: Text format. Each line ends with a carriage-return/line-feed combination. Tab characters separate fields within a line. A NULL character signals the end of the data.
CF_DSPTEXT: Text display format associated with private format.
CF_BITMAP: Bit map.
CF_DSPBITMAP: Bit-map display format associated with private format.
CF_METAFILE: Metafile.
CF_DSPMETAFILE: Metafile display format associated with private format.
CF_PALETTE: Palette.

Returns

ulRet (ULONG) - returns
Handle to the clipboard data.
Format does not exist, or an error occurred
Other
Handle to the clipboard data.

Remarks

The returned data handle must not be used after the WinCloseClipbrd function is called. For this reason, the application must either copy the data (if required for long-term use) or process the data before the WinCloseClipbrd function is called. The application must neither free the data handle itself, nor leave it locked in any way.

Information about the format of the data in the clipboard can be obtained from WinQueryClipbrdFmtInfo.

Example Code

This example obtains a handle to the current clipboard data of text format.

#define INCL_WINCLIPBOARD
#include <os2.h>

HAB hab;
/* . */
ULONG hclipbrdData;

hclipbrdData = WinQueryClipbrdData(hab, CF_TEXT);
