GPR_$SET_INPUT_SID GPR Calls GPR_$SET_INPUT_SID
NAME
gpr_$set_input_sid - specifies the input pad for graphics input.
FORMAT
gpr_$set_input_sid (stream_id, status)
DESCRIPTION
This routine specifies the input pad from which graphics input is to be
taken.
Input Parameters
stream_id
The stream-id that GPR software will use for input in frame mode, in
stream_$id_t format. The stream must be a Display Manager input
pad.
Output Parameters
status
Completion status, in status_$t format.
NOTES
Programs use this call only when they call input routines in frame mode
(gpr_$event_wait and gpr_$cond_event_wait).
If this routine is not called, the default stream ID is stream_$stdin (a
stream id of zero).
To work properly, the input pad must be the pad associated with the tran-
script pad passed to gpr_$init. stream_$stdin is associated with
stream_$stdout in this way in a normal Shell process window. Other pro-
cess input pads derive their association from the pad_$create call that
created them.
