fn register_eventfd_async(self: *IO_Uring, fd: os.fd_t) !void

Registers the file descriptor for an eventfd that will be notified of completion events on an io_uring instance. Notifications are only posted for events that complete in an async manner. This means that events that complete inline while being submitted do not trigger a notification event. Only a single eventfd can be registered at any given point in time.

Parameters

self: *IO_Uring,
fd: os.fd_t,
