instance method

Fiber::Scheduler#process_wait

process_wait(pid, flags)

VALUE
rb_fiber_scheduler_process_wait(VALUE scheduler, rb_pid_t pid, int flags)
{
    VALUE arguments[] = {
        PIDT2NUM(pid), RB_INT2NUM(flags)
    };

    return rb_check_funcall(scheduler, id_process_wait, 2, arguments);
}

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 return a Process::Status instance.
