POSIX

POSIX is a registered trademark from the IEEE. The following assertions are derived from copyrighted material. Original text and copyright information can be found at http://www.opengroup.org.

Here is what POSIX requires for this function:

If sem_unlink has not been called after sem_open for this semaphore, the function has no effect on the semaphore.
If sem_unlink as been called, the semaphore is no longer accessible after the last process which opened it calls sem_close.
The function returns 0 on success and -1 otherwise.

Conformance Status

Assertion 1 is not tested yet. A new testcase will be written.
Assertion 2 is not tested yet. There is no way to access the semaphore once latest sem_close has been opened, so this can not be tested (any call to sem_open refer to a new semaphore after sem_unlink has been called).
Assertion 3 is already tested.
