Synopsis

Tries to lock the mutex in shared mode. Returns immediately. On successful lock acquisition returns true, otherwise returns false.
This function is allowed to fail spuriously and return false even if the mutex is not currenly exclusively locked by any other thread.
Prior unlock() operation on the same mutex synchronizes-with (as defined in std::memory_order) this operation if it returns true.
The behavior is undefined if the calling thread already owns the mutex in any mode.
