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 DLL 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.
