blanktime(3G)

NAME
     blanktime - sets the screen blanking timeout

C SPECIFICATION
     void blanktime(long count)

PARAMETERS
     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
     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
     This routine is available only in immediate mode.
