is_memory_bitmap(3) Tells if a bitmap is a memory bitmap. Allegro game programming library.


#include <allegro.h>

int is_memory_bitmap(BITMAP *bmp);


Returns TRUE if bmp is a memory bitmap, ie. it was created by calling create_bitmap() or loaded from a grabber datafile or image file. Memory bitmaps can be accessed directly via the line pointers in the bitmap structure, eg. bmp->line[y][x] = color.
