L_ReleaseBitmap

#include "l_bitmap.h"

L_LTKRN_API L_VOID L_ReleaseBitmap(pBitmap)

pBITMAPHANDLE pBitmap;

pointer to the bitmap handle

Releases memory back to Windows, reversing the action of the L_AccessBitmap function. This has the same effect as the Windows C API GlobalUnlock function.

Parameter

Description

pBitmap

Pointer to the bitmap handle referencing the bitmap to be released.

Returns

None.

Comments

Use this along with the L_AccessBitmap function to control the access to bitmap data in memory. Any attempt to access the image data after calling L_ReleaseBitmap will result in an application error.

You should call this function whenever the image is not used, so that Windows can manage its memory properly.
