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().
