void release( std::ptrdiff_t update = 1 ); (since C++20)

waiting for the counter to be greater than 0, such as due to being blocked in
acquire, will subsequently be unblocked.

of the internal counter.

Parameters¶

update - the amount to increment the internal counter by

Exceptions¶

May throw std::system_error.
