Function libaeron_sys::aeron_async_add_subscription_get_registration_id

pub unsafe extern "C" fn aeron_async_add_subscription_get_registration_id(
    add_subscription: *mut aeron_async_add_subscription_t
) -> i64

Gets the registration id for addition of the subscription. Note that using this after a call to poll the succeeds or errors is undefined behaviour. As the async_add_subscription_t may have been freed.

@param add_subscription used to check for completion. @return registration id for the subscription.
