CBL_MUTEX_OPEN_INTRA

Create an intra-process mutex.

Note: This routine is not supported in JVM COBOL.

Syntax:

call "CBL_MUTEX_OPEN_INTRA" using by reference mutex-handle
                            by value           open-flags

	Using call prototype (see Key)	Picture
`mutex-handle`	cblt-pointer.	usage pointer.
`open-flags`	cblt-os-flags.	pic x(4) comp-5 or pic x(8) comp-5 (64-bit native programs only)

A value that determines how the mutex is to be opened:

Bit 0

0	Mutex is not acquired by the current thread at creation.
1	Mutex is acquired by the current thread at creation.

Remaining bits

Reserved. Set to zero

mutex-handle: Mutex handle
