clear_zbuffer(3)		 Allegro manual 		clear_zbuffer(3)

NAME
     clear_zbuffer  - Writes a depth value into the given Z-buffer. Allegro game
     programming library.

SYNOPSIS
     #include <allegro.h>

     void clear_zbuffer(ZBUFFER *zbuf, float z);

DESCRIPTION
     Writes z into the given Z-buffer (0 means far away). This	function  should
     be  used  to initialize the Z-buffer before each frame. Actually, low-level
     routines compare depth of the current pixel with 1/z: for example,  if  you
     want  to  clip  polygons farther than 10, you must call clear_zbuffer(zbuf,
     0.1).

SEE ALSO
     create_zbuffer(3), set_zbuffer(3), destroy_zbuffer(3), exzbuf(3)

Allegro 			  version 4.4.3 		clear_zbuffer(3)
