Response Obtain the process ID of the caller to CONTROL by a call to LASTRECEIVE or
RECEIVEINFO. The response, if any, is application dependent.
-33 PROCESS SETMODE
Cause Another process referred to the receiving process in a call to the SETMODE or
SETMODENOWAIT procedure.
Format The operating system sends the process the following message, provided the process has
opened its $RECEIVE file to receive file management system messages either by setting the
FILE_OPEN_ procedure parameter options.<15>to 0 or the OPEN procedure parameter flags.<1>to
1:
sysmsg[0] = -33
sysmsg[1] = function parameter to caller's SETMODE or
SETMODENOWAIT
sysmsg[2] = param1 parameter to caller's SETMODE
or SETMODENOWAIT
sysmsg[3] = param2 parameter to caller's SETMODE
or SETMODENOWAIT
If the receiving process can handle requests for last parameter information (by setting
param1.<15>in a SETMODE 80 call), the flags word is included:
sysmsg [4] = Flags word:
.<13> = 1 if param1 was supplied in the call to
SETMODE
.<14> = 1 if param2 was supplied in the call
to SETMODE
.<15> = 1 if last-params was supplied in the
call to SETMODE
Response Obtain the process ID of the caller to SETMODE or SETMODENOWAIT by a call to
LASTRECEIVE or RECEIVEINFO. The response, if any, is application dependent.
A process that receives the extended (five-word) SETMODE message can return a value to be
placed in the last-params parameter of the SETMODE caller. The process should call REPLY with
a buffer that has the format:
replymsg[0] = -33
replymsg[1] = The previous value of param1
replymsg[2] = The previous value of param2
Supplying a reply when none is needed will not cause an error.
-34 PROCESS RESETSYNC
Cause Another process called the RESETSYNC procedure while referring to the receiver process
file. A call to the CHECKPOINT procedure might contain an implicit call to RESETSYNC.
Format The operating system sends the process the following message, provided the process has
opened its $RECEIVE file to receive file management system messages either by setting the
FILE_OPEN_ procedure parameter options.<15>to 0 or the OPEN procedure parameter flags.<1>to
1:
sysmsg[0] = -34
Response Obtain the process ID of the caller to RESETSYNC by a call to LASTRECEIVE or
RECEIVEINFO. A server process using the sync ID mechanism should clear its local copy of the
sync ID value. Corrective action, if any, is application dependent.
