std::unique_lock
mutex_type* release() noexcept;
 (since C++11)

Breaks the association of the associated mutex, if any, and *this.

No locks are unlocked. If *this held ownership of the associated mutex prior to the call, the caller is now responsible to unlock the mutex.

Parameters

Return value

Pointer to the associated mutex or a null pointer if there was no associated mutex.
