fli_pal_dirty_from(3)		Allegro	manual		 fli_pal_dirty_from(3)

NAME
       fli_pal_dirty_from,  fli_pal_dirty_to  -	 Indicate  which  parts	of the
       palette have changed. Allegro game programming library.

SYNOPSIS
       #include	<allegro.h>

       extern int fli_pal_dirty_from;

       extern int fli_pal_dirty_to;

DESCRIPTION
       These variables are set by next_fli_frame() to indicate which  part  of
       the  fli_palette	 has  changed  since  the last call to reset_fli_vari-
       ables().	If fli_pal_dirty_from is greater  than	fli_pal_dirty_to,  the
       palette	 has  not  changed,  otherwise	colors	fli_pal_dirty_from  to
       fli_pal_dirty_to	(inclusive) have altered. You can use these  when  up-
       dating	the   hardware	 palette,   to	 avoid	unnecessary  calls  to
       set_palette(). Example:

	  if (fli_pal_dirty_from <= fli_pal_dirty_to)
	     set_palette_range(fli_palette, fli_pal_dirty_from,
			       fli_pal_dirty_to, 1);
