NAME

       al_clear_depth_buffer - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              void al_clear_depth_buffer(float z)

DESCRIPTION

       Clear  the  depth buffer (confined by the clipping rectangle) to the given value.  A depth
       buffer is only available if it was requested with  al_set_new_display_option(3alleg5)  and
       the  requirement  could be met by the al_create_display(3alleg5) call creating the current
       display.    Operations   involving   the   depth   buffer    are    also    affected    by
       al_set_render_state(3alleg5).

       For  example,  if  ALLEGRO_DEPTH_FUNCTION  is set to ALLEGRO_RENDER_LESS then depth buffer
       value of 1 represents infinite distance, and thus is a good value to use when clearing the
       depth buffer.
