Nicht-Member-Funktionen

swap(std::shared_lock)

 

template< class Mutex > void swap( shared_lock<Mutex>& lhs,            shared_lock<Mutex>& rhs ) noexcept;		(seit C++14)

Spezialisiert den std::swap Algorithmus für std::shared_lock. Vertauscht den Zustand von lhs mit dem von rhs. Ruft effektiv lhs.swap(rhs) auf.

Parameter

lhs, rhs

-

Lock-Wrapper, deren Zustände vertauscht werden sollen

Rückgabewert

(keine)
