System Functions (n - p) PUT_SETMODE(2)
Process message
Issuing a PUT_SETMODE() call to a file representing another process causes a
system message -33 (process SETMODE) to be sent to that process.
You can identify the process that called PUT_SETMODE() in a subsequent call
to the Guardian FILE_GETRECEIVEINFO_ (or LASTRECEIVE or
RECEIVEINFO) procedure. For a list of all system messages sent to processes,
see the Guardian Procedure Errors and Messages Manual.
RETURN VALUES
The PUT_SETMODE() function returns 0 (zero) upon successful completion. Otherwise, this
function returns a nonzero Guardian file-system error number that indicates the outcome of the
operation.
For information about Guardian file-system error numbers, see the Guardian Procedure Errors
and Messages Manual.
ERRORS
None. This function does not set the errno variable.
