== NAME

|
nng_mtx_unlock - unlock mutex
|
|
|
|
== SYNOPSIS
|
|
|
|
[source, c]
|
|
----
|
|
#include <nng/nng.h>
|
|
#include <nng/supplemental/util/platform.h>
|
|
|
|
void nng_mtx_unlock(nng_mtx *mtx);
|
|
----
|
|
|
|
== DESCRIPTION
|
|
|
|
The `nng_mtx_unlock()` relinquishes ownership of the mutex _mtx_ that
|
|
was previously acquired via xref:nng_mtx_lock.3supp.adoc[`nng_mtx_lock()`].
|
|
|
|
IMPORTANT: A mutex can _only_ be unlocked by the thread that locked it.
|
|
Attempting to unlock a mutex that is not owned by the caller will result
|
|
in undefined behavior.
|
|
|
|
== RETURN VALUES
|
|
|
|
None.
|
|
|
|
== ERRORS
|
|
|
|
None.
