`std::unique_lock::operator bool` Member Function

Check whether or not *this owns a lock on a mutex.

explicit operator bool() const;

Returns:: this->owns_lock().
Throws:: Nothing.
Note:: This is an explicit conversion operator, so is only implicitly called in contexts where the result is used as a boolean, and not where the result would be treated as an integer value 0 or 1. This behaviour is emulated on compilers that do not support C++11 explicit operators.
