GPR_$SET_BLANK_TIMEOUT            GPR Calls             GPR_$SET_BLANK_TIMEOUT


NAME
     gpr_$set_blank_timeout - establishes the time period that the system
     waits before it shuts off the screen.

FORMAT
     gpr_$set_blank_timeout (timeout, status)

DESCRIPTION
     This routine establishes the time period that the system waits before it
     shuts off the screen.  The time period is measured from the last input
     event.  This routine is similar to the shell command scrto [n].

   Input Parameters
     timeout
          Amount of time the system will wait before the screen is blanked
          out.  Type is in time_$clock_t format.  In FORTRAN, declare a two-
          element array of int*4.  Also declare a two-element dummy array of
          int*2.  EQUIVALENCE the dummy array with the second element of the
          int*4 array.  Use the first element of the int*4 array for
          timeout.low32.  Use the first element of the dummy array for
          timeout.high16.

   Output Parameters
     status
          Completion status, in status_$t format.

NOTES
     The time_$clock_t  data  type  is  listed  in  /sys/ins/base.ins.pas  and
     /usr/apollo/include/base.h.   This  data  type  is described in detail in
     Programming with General System Calls.
