SYS$DLCEFC (OpenVMS) SYS$DLCEFC (OpenVMS)
NAME
semctl - perform semaphore control operations
SYS$DLCEFC - Delete common event flag cluster
EXPLAINATION
The Digital UNIX semctl system call is similar to the OpenVMS
SYS$DLCEFC system service in that they both delete a process synchro‐
nization set. The semctl function can be called with a command of
IPC_RMID to remove the semaphore set from the system. Unlike the Open‐
VMS call, semctl will not mark the semaphore set for deletion, but will
instead delete it immediately. Any process later accessing this sema‐
phore set will be returned an error
