std::counting_semaphore
Member functions
Operations
counting_semaphore::release
Constants
void release( std::ptrdiff_t update = 1 );
(since C++20)
Atomically increments the internal counter by the value of update. Any thread(s) waiting for the counter to be greater than 0, such as due to being blocked in acquire, will subsequently be unblocked.
This operation strongly happens before invocations of try_acquire that observe the result of the effects.
[edit] Preconditions
Both update >= 0 and update <= max() - counter are true, where counter is the value of the internal counter.
[edit] Parameters
update
-
the amount to increment the internal counter by
[edit] Exceptions
May throw std::system_error .
