nng_mtx_lock(3supp)
NAME
nng_mtx_lock - lock mutex
SYNOPSIS
DESCRIPTION
The nng_mtx_lock()
acquires exclusive ownership of the mutex mtx.
If the lock is already owned, this function will wait until the current
owner releases it with nng_mtx_unlock()
.
If multiple threads are waiting for the lock, the order of acquisition is not specified.
A mutex can only be unlocked by the thread that locked it. |
Mutex locks are not recursive; attempts to reacquire the same mutex may result in deadlock or aborting the current program. It is a programming error for the owner of a mutex to attempt to reacquire it. |
RETURN VALUES
None.
ERRORS
None.
