std::timed_mutex::try_lock_for
From cppreference.com
< cpp | thread | timed mutex
template< class Rep, class Period >
bool try_lock_for( const std::chrono::duration<Rep,Period>& timeout_duration ); |
(since C++11) | |
Tries to lock the mutex. Blocks until specified timeout_duration
has elapsed or the lock is acquired, whichever comes first. On successful lock acquisition returns true, otherwise returns false.
A steady clock is used to measure the duration. This function may block for longer than timeout_duration
due to scheduling or resource contention delays.
The behavior is undefined if the mutex is not unlocked before being destroyed, i.e. some thread still owns it.
