std::unique_lock<Mutex>::try_lock_until
< cpp | thread | unique lock
template< class Clock, class Duration > bool try_lock_until( const std::chrono::time_point<Clock,Duration>& timeout_time ); |
(since C++11) | |
Tries to lock the associated mutex. Blocks until specified timeout_time
has been reached or the lock is acquired, whichever comes first. On successful lock acquisition returns true, otherwise returns false. May block for longer than until timeout_time
has been reached.
Effectively calls mutex()->try_lock_until(timeout_time)
std::system_error is thrown if there is no associated mutex or if the mutex is already locked.
Parameters
timeout_time | - | maximum time point to block until |
Return value
true if the ownership of the mutex has been acquired successfully, false otherwise.
Exceptions
- Any exceptions thrown by mutex()->try_lock_until(timeout_time)
- If there is no associated mutex, std::system_error with an error code of std::errc::operation_not_permitted
- If the mutex is already locked, std::system_error with an error code of std::errc::resource_deadlock_would_occur
