pSOS+ System Calls sm_delete
Notes

1. Once created, a semaphore is generally used by multiple tasks for
communication and synchronization. There is rarely a reason for deleting a
semaphore, even when it is no longer used, except to allow reuse of the SMCB.
2. The calling task can be preempted, if a task waiting at the deleted semaphore
has higher priority.
Multiprocessor Considerations
If smid identifies a global semaphore, sm_delete will notify the master node so
that the semaphore can be removed from its Global Object Table. Thus, deletion of a
global semaphore always causes activity on the master node.
