create_video_bitmap - Creates a video memory bitmap. Allegro game programming library.
BITMAP *create_video_bitmap(int width, int height);
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.
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().

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it
