counting_semaphore::max
constexpr std::ptrdiff_t max() noexcept;
(since C++20)
Returns the internal counter's maximum possible value, which is greater than or equal to LeastMaxValue.
[edit] Return value
The internal counter's maximum possible value, as a std::ptrdiff_t .
[edit] Notes
For specialization binary_semaphore, LeastMaxValue is equal to 1.
As its name indicates, the LeastMaxValue is the minimum max value, not the actual max value. Thus max() can yield a number larger than LeastMaxValue.
