NAME

std::recursive_mutex::unlock - std::recursive_mutex::unlock

Synopsis

void unlock(); (since C++11)

Unlocks the mutex if its level of ownership is 1 (there was exactly one more call to
lock() than there were calls to unlock() made by this thread), reduces the level of
ownership by 1 otherwise.

The mutex must be locked by the current thread of execution, otherwise, the behavior
is undefined.

This operation synchronizes-with (as defined in std::memory_order) any subsequent
lock operation that obtains ownership of the same mutex.

Parameters

(none)

Return value

(none)

Exceptions

Throws nothing.

Notes

unlock() is usually not called directly: std::unique_lock and std::lock_guard are
used to manage exclusive locking.
