instance method

Fiber::SchedulerInterface#process_wait

process_wait(pid, flags)

static VALUE
rb_fiber_scheduler_interface_process_wait(VALUE self)
{
}

Invoked by Process::Status.wait in order to wait for a specified process. See that method description for arguments description.

Suggested minimal implementation:

Example

Thread.new do
  Process::Status.wait(pid, flags)
end.value

This hook is optional: if it is not present in the current scheduler, Process::Status.wait will behave as a blocking method.

Expected to returns a Process::Status instance.
