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.
