template<class Rep,class Period> bool try_lock_for(conststd::chrono::duration<Rep,Period>& timeout_duration); | (since C++14) | |
Tries to lock the associated mutex in shared mode. Blocks until specifiedtimeout_duration has elapsed or the lock is acquired, whichever comes first. On successful lock acquisition returnstrue, otherwise returnsfalse. Effectively callsmutex()->try_lock_shared_for(timeout_duration).
This function may block for longer thantimeout_duration due to scheduling or resource contention delays.
The standard recommends that a steady clock is used to measure the duration. If an implementation uses a system clock instead, the wait time may also be sensitive to clock adjustments.
std::system_error is thrown if there is no associated mutex or if the mutex is already locked.
The behavior is undefined ifMutex does not meet theSharedTimedLockable requirements.
