std::counting_semaphore
Member functions
Operations
counting_semaphore::try_acquire
Constants
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.
[edit] Return value
true if it decremented the internal counter, otherwise false.
[edit] 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.

(public member function) [edit]
