request_refresh_rate(3)		Allegro	manual	       request_refresh_rate(3)

NAME
       request_refresh_rate  - Requests	a specific refresh rate	during graphic
       mode switch. Allegro game programming library.

SYNOPSIS
       #include	<allegro.h>

       void request_refresh_rate(int rate);

DESCRIPTION
       Requests	that the next call to set_gfx_mode() try to use	the  specified
       refresh	rate, if possible. Not all drivers are able to control this at
       all, and	even when they can, not	all rates  will	 be  possible  on  all
       hardware,  so  the  actual settings may differ from what	you requested.
       After you call set_gfx_mode(), you can use get_refresh_rate()  to  find
       out  what was actually selected.	At the moment only the DOS VESA	3.0, X
       DGA 2.0 and some	Windows	DirectX	drivers	 support  this	function.  The
       speed  is  specified in Hz, eg. 60, 70. To return to the	normal default
       selection, pass a rate value of zero. Example:

	  request_refresh_rate(60);
	  if (set_gfx_mode(GFX_AUTODETECT, 640,	480, 0,	0) != 0)
	     abort_on_error("Couldn't set graphic mode!");
	  if (get_refresh_rate() != 60)
	     abort_on_error("Couldn't set refresh rate to 60Hz!");
