set_clip_state(3alleg4) 					  Allegro manual					   set_clip_state(3alleg4)

NAME
       set_clip_state - Turns on or off the clipping of a bitmap. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       void set_clip_state(BITMAP *bitmap, int state)

DESCRIPTION
       Turns  on  (if  state  is non-zero) or off (if state is zero) clipping for the specified bitmap. Turning clipping off may slightly speed up
       some drawing operations (usually a negligible  difference, although every little helps) but will result in your program	dying  a  horrible
       death if you try to draw beyond the edges of the bitmap.
