Good day,

i want to know if it is possible to prevent UNDOING on s=E9maphore
operation after calling semop with SEM_UNDO option. i know that using
ipc_nowait don't produce undo action but the call will not block "thing
i don't want". I think that there is a missed option in the design of
the function semop, how may it possible to force undoing changes on
semaphore after the process exit? Perhaps we better think that a
process can take with him some tickets when it die.

so what i want to know is how a make a process terminate without
undoing its operations on the semaphore.


thank u.
