get_color_depth(3)              Allegro manual              get_color_depth(3)

NAME
       get_color_depth - Returns the current pixel color depth. Allegro game
       programming library.

SYNOPSIS
       #include <allegro.h>

       int get_color_depth(void);

DESCRIPTION
       Returns the current pixel format. This can be very useful to know in
       order to write generic functions which select a different code path
       internally depending on the color depth being used.

       Note that the function returns whatever value you may have set
       previously with set_color_depth(), which can be different from the
       current color depth of the screen global variable. If you really need
       to know the color depth of the screen, use bitmap_color_depth().
