GreDeleteBitmap

GreDeleteBitmap deletes the bit map identified by hbm. If the bit map is currently selected into a DC, GreDeleteBitmap returns an error.

This function is supported by the graphics engine.

Syntax

GreDeleteBitmap(hbm, pInstance, lFunction);

Parameters

hbm (HBITMAP) - input

Bit-map handle.

pInstance (PVOID) - input

Pointer to instance data.

lFunction (ULONG) - input

High-order WORD=flags; low-order WORD=NGreDeleteBitmap.

Returns

fSuccess (BOOL) - returns

Return codes.

On completion, the handling routine must return BOOLEAN (fSuccess).

• TRUE Successful
• FALSE Error

Possible Errors Detected: When an error is detected, the graphics engine calls WinSetErrorInfo to post the condition. Reasons for failure of this function include:

• PMERR_BITMAP_IS_SELECTED
• PMERR_DEV_FUNC_NOT_INSTALLED
• PMERR_HBITMAP_BUSY
• PMERR_INSUFFICIENT_MEMORY
• PMERR_INV_HBITMAP
• PMERR_INV_HDC
• PMERR_INV_INFO_TABLE
• PMERR_INV_LENGTH_OR_COUNT
• PMERR_INV_SCAN_START

Sample

#define INCL_GRE_DEVSUPPORT
#include <os2.h>

HBITMAP    hbm;        /*  Bit-map handle. */
PVOID      pInstance;  /*  Pointer to instance data. */
ULONG      lFunction;  /*  High-order WORD=flags; low-order WORD=NGreDeleteBitmap. */
BOOL       fSuccess;   /*  Return codes. */

fSuccess = GreDeleteBitmap(hbm, pInstance,
             lFunction);
