desktop_color_depth(3alleg4)    Allegro manual    desktop_color_depth(3alleg4)



NAME
       desktop_color_depth - Finds out the desktop color depth. Allegro game
       programming library.

SYNOPSIS
       #include <allegro.h>


       int desktop_color_depth();

DESCRIPTION
       Finds out the currently selected desktop color depth. You can use this
       information to make your program use the same color depth as the
       desktop, which will likely make it run faster because the graphic
       driver won't be doing unnecessary color conversions behind your back.

       Under some OSes, switching to a full screen graphics mode may
       automatically change the desktop color depth. You have, therefore, to
       call this function before setting any graphics mode in order to
       retrieve the real desktop color depth. Example:

          allegro_init();
          ...
          if ((depth = desktop_color_depth()) != 0) {
             set_color_depth(depth);
          }

RETURN VALUE
       Returns the color depth or zero on platforms where this information is
       not available or does not apply.
