create_zbuffer(3alleg4) 					  Allegro manual					   create_zbuffer(3alleg4)

NAME
       create_zbuffer - Creates a Z-buffer for a bitmap. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       ZBUFFER *create_zbuffer(BITMAP *bmp);

DESCRIPTION
       Creates	a  Z-buffer using the size of the BITMAP you are planning to draw on. Several Z-buffers can be defined but only one can be used at
       the same time, so you must call set_zbuffer() to make this Z-buffer active.

RETURN VALUE
       Returns the pointer to the ZBUFFER or NULL if there was an error. Remember to destroy the ZBUFFER once you are done with it, to avoid  hav-
       ing memory leaks.
