std::counti...try_acquire(3) C++ Standard Libary std::counti...try_acquire(3) NAME std::counting_semaphore::try_acquire - std::counting_semaphore::try_ac- quire Synopsis bool try_acquire() noexcept; (since C++20) Tries to atomically decrement the internal counter by 1 if it is greater than 0; no blocking occurs regardless. Return value true if it decremented the internal counter, otherwise false. Notes Implementations are allowed to fail to decrement the counter even if it was greater than 0 - i.e., they are allowed to spuriously fail and return false.
