NAME¶

std::timed_mutex::try_lock - std::timed_mutex::try_lock

Synopsis¶

bool try_lock(); (since C++11)

Tries to lock the mutex. 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 currently locked by any other thread.

If try_lock is called by a thread that already owns the mutex, the behavior is
undefined.

Prior unlock() operation on the same mutex synchronizes-with (as defined in
std::memory_order) this operation if it returns true. Note that prior lock() does
not synchronize with this operation if it returns false.

Parameters¶

(none)

Return value¶

true if the lock was acquired successfully, otherwise false.

Exceptions¶

Throws nothing.
