explicit operator bool() const noexcept;		(seit C++11)

Prüft, ob *this ein gesperrtes Mutex besitzt oder nicht. Ruft effektiv owns_lock() auf.

Parameter

(keine)

Rückgabewert

true, wenn *this ein zugeordnetes Mutex hat und dessen Besitz erworben hat, andernfalls false.

Siehe auch

owns_lock

prüft, ob die Sperre den zugehörigen Mutex besitzt (d.h. gesperrt hat) (public member function)
