#include "l_bitmap.h"

L_LTFIL_API L_INT L_LoadExtensionStamp(pExtensionList, pBitmap, uStructSize)

pEXTENSIONLIST pExtensionList;	/* pointer to a structure */
pBITMAPHANDLE pBitmap;	/* pointer to a bitmap handle */
L_UINT uStructSize;	/* size in bytes, of the structure pointed to by pBitmap */

Loads a stamp from the specified extension list.

Parameter	Description
pExtensionList	Pointer to the EXTENSIONLIST structure that contains the stamp to load.
pBitmap	Pointer to the bitmap handle that references the bitmap to be updated with the stamp loaded from the specified extension list.
uStructSize	Size in bytes, of the structure pointed to by pBitmap, for versioning. Use sizeof(BITMAPHANDLE).

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

The extensions referenced by the pExtensionList parameter must be loaded by calling the L_ReadFileExtensions function.
