NAME    [Toc]    [Back]

     blanktime - sets the screen blanking timeout

C SPECIFICATION    [Toc]    [Back]

     void blanktime(long count)

PARAMETERS    [Toc]    [Back]

     count   expects the number	of graphics timer events after which to	blank
	     the current screen.  The frequency	of graphics timer events is
	     returned by the getgdesc inquiry GD_TIMERHZ.

DESCRIPTION    [Toc]    [Back]

     By	default, a screen blanks (turns	black) after the system	receives no
     input for 10-15 minutes.  This protects the monitor.  Use blanktime to
     change the	amount of time the system waits	before it blanks a screen.  It
     affects the screen	on which the current window is displayed.

     To	calculate the value of count, simply multiply the desired blanking
     latency period (in	seconds) by getgdesc(GD_TIMERHZ).

     You can disable screen blanking by	calling	this routine with a count of
     zero.

NOTE    [Toc]    [Back]

     This routine is available only in immediate mode.
