  • Cikk

Constructs a lock_guard object.

explicit lock_guard(mutex_type& Mtx);
lock_guard(mutex_type& Mtx, adopt_lock_t);

Parameters

  • Mtx
    A mutex type object.

Remarks

The first constructor constructs an object of type lock_guard and locks Mtx. If Mtx is not a recursive mutex, it must be unlocked when this constructor is called.

The second constructor does not lock Mtx. Mtx must be locked when this constructor is called. The constructor throws no exceptions.

Requirements

Header: mutex

Namespace: std
