# std::timed_mutex

From cppreference.com
< cpp‎ | thread

Defined in header `<mutex>` |  |
class timed_mutex; |  | (since C++11)

The `timed_mutex` class is a synchronization primitive that can be used to protect shared data from being simultaneously accessed by multiple threads.

In a manner similar to `mutex`, `timed_mutex` offers exclusive, non-recursive ownership semantics. In addition, `timed_mutex` provides the ability to attempt to claim ownership of a `timed_mutex` with a timeout via the `try_lock_for()` and `try_lock_until()` methods.

The `timed_mutex` class satisfies all requirements of `TimedMutex` and `StandardLayoutType`.
