CBL_SEMAPHORE_RELEASE

Releases one of the resources represented by the semaphore by incrementing the associated count.

Note: This routine is not supported in JVM COBOL.

Syntax:

call "CBL_SEMAPHORE_RELEASE" using by value semaphore-handle

Parameters:

	Using call prototype (see Key)	Picture
`semaphore-handle`	cblt-pointer	usage pointer.

On Entry:

semaphore-handle

Semaphore handle.

On Exit:

return-code

A value of 0 indicates that the call was successful. Any other value indicates an error. See RETURN-CODE Values For Synchronization Routines

Comments:

If the count was zero before the increment, and some other threads are blocked in a CBL_SEMAPHORE_ACQUIRE call waiting for the count to become non-zero, then one of those threads is released, so it can decrement the count and return from CBL_SEMAPHORE_ACQUIRE.

Behavior is undefined if semaphore-handle is invalid.
