NAME

       create_video_bitmap - Creates a video memory bitmap. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       BITMAP *create_video_bitmap(int width, int height);

DESCRIPTION

       Allocates  a  video  memory  bitmap  of the specified size. This can be used to allocate offscreen video memory for storing source graphics
       ready for a hardware accelerated blitting operation, or to create multiple video memory pages  which  can  then	be  displayed  by  calling
       show_video_bitmap().  Read the introduction of this chapter for a comparison with other types of bitmaps and other specific details.

       Warning:  video memory bitmaps are usually allocated from the same space as the screen bitmap, so they may overlap with it; it is therefore
       not a good idea to use the global screen at the same time as any surfaces returned by this function.

RETURN VALUE

       Returns a pointer to the bitmap on success, or NULL if you have run out of video ram. Remember to destroy this bitmap before any subsequent
       call to set_gfx_mode().
