desktop_color_depth(3)		Allegro	manual		desktop_color_depth(3)

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 desk-
       top, 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 automati-
       cally 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.
