LOCRINOWNER
NM and CM callable.
Determines process identification number (PIN) of the process that locked
a local resource identification number (RIN).
Syntax
_____________________________________

| I16 I16V |
| pin:=LOCRINOWNER(rinnum); |
_____________________________________
Functional Return
pin 16-bit signed integer (assigned functional return)
If the RIN is locked by the parent of the calling
process, LOCRINOWNER returns 0. If the RIN is
locked by any other process in your process
structure, LOCRINOWNER returns the PIN of that
process.
Parameters
rinnum 16-bit signed integer by value (required)
Passes the number of the local RIN for which the
PIN of the locking process is to be determined.
The range of valid values is from 1 to the value
specified in the rincount parameter of the
GETLOCRIN intrinsic.
Operation Notes
The LOCRINOWNER intrinsic determines the PIN of the process that has a
particular local RIN locked. After a process has acquired local RINs,
other processes in the process structure can lock and unlock these RINs.
Condition Codes
CCE (2) Request granted.
CCG (0) Request denied. The local RIN specified by rinnum
is not currently locked by any process.
CCL (1) Request denied. The rinnum parameter was invalid
(that is, rinnum was less than or equal to 0,
greater than the RIN table size, or greater than
the number of local RINs currently allocated to
this process structure).
