Method: Fiber::SchedulerInterface#io_wait

Defined in:

cont.c

#io_wait(io, events, timeout) ⇒ Object

Invoked by IO#wait, IO#wait_readable, IO#wait_writable to ask whether the specified descriptor is ready for specified events within the specified timeout.

events is a bit mask of IO::READABLE, IO::WRITABLE, and IO::PRIORITY.

Suggested implementation should register which Fiber is waiting for which resources and immediately calling Fiber.yield to pass control to other fibers. Then, in the #close method, the scheduler might dispatch all the I/O resources to fibers waiting for it.

Expected to return the subset of events that are ready immediately.
