std::shared_lock
Member functions
shared_lock::operator=
Shared locking
Modifiers
Observers
Non-member functions
shared_lock& operator=( shared_lock&& other ) noexcept;
(since C++14)
Move assignment operator. Equivalent to shared_lock{std::move(other)}.swap(*this); return *this;.
If other is the same object as *this, there is no effect.
Otherwise, if prior to this call *this has an associated mutex ((mutex() returns a non-null pointer) and has acquired ownership of it (owns() returns true), the mutex is unlocked by calling unlock_shared() . After this call, other has no associated mutex.
[edit] Parameters
other
-
another
shared_lock to replace the state with
[edit] Return value
*this
