class condition_variable_any; |
(since C++11) | |
The condition_variable_any class is a generalization of std::condition_variable. Whereas std::condition_variable works only on
std::unique_lock
<
std::mutex
>
, condition_variable_any can operate on any lock that meets the BasicLockable
See std::condition_variable for the description of the semantics of condition variables.
The class std::condition_variable_any is a StandardLayoutType. It is not CopyConstructible, MoveConstructible, CopyAssignable, or MoveAssignable
If the lock is std::unique_lock < std::mutex > , std::condition_variable

Notes
std::condition_variable_any can be used with std::shared_lock in order to wait on a std::shared_mutex
A possible use for std::condition_variable_any with custom
Lockable
types is to provide convenient interruptible waits: the custom lock operation would both lock the associated mutex as expected, and also perform the necessary setup to notify this condition variable when the interrupting signal is received.[1]
