std::counting_semaphore
constexpr std:: ptrdiff_t max ( ) noexcept ;
(C++20부터)

내부 카운터의 가능한 최대값을 반환하며, 이 값은 LeastMaxValue 보다 크거나 같습니다.

반환값

내부 카운터의 가능한 최댓값을 std::ptrdiff_t 로 나타낸 값입니다.

참고 사항

특수화 binary_semaphore 의 경우, LeastMaxValue 는 1 과 동일합니다.

이름에서 알 수 있듯이, LeastMaxValue 는 최소 최댓값이지 실제 최댓값이 아닙니다. 따라서 max ( ) 는 LeastMaxValue 보다 큰 숫자를 반환할 수 있습니다.
