Nicht-Member-Funktionen

swap(std::shared_lock)

 

explicit operator bool() const noexcept;		(seit C++14)

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 gemeinsame Sperrung erworben hat, andernfalls false.

Siehe auch

owns_lock

testet, ob der Lock den zugehörigen Mutex besitzt (public member function)
