SYNOPSIS
#include <nng/nng.h>
#include <nng/supplemental/util/platform.h>
void nng_mtx_lock(nng_mtx *mtx);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.
