/*
|
|
* call-seq:

* tcpserver.accept_nonblock => tcpsocket
|
|
*
|
|
* Accepts an incoming connection using accept(2) after
|
|
* O_NONBLOCK is set for the underlying file descriptor.
|
|
* It returns an accepted TCPSocket for the incoming connection.
|
|
*
|
|
* === Example
|
|
* require 'socket'
|
|
* serv = TCPServer.new(2202)
|
|
* begin # emulate blocking accept
|
|
* sock = serv.accept_nonblock
|
|
* rescue IO::WaitReadable, Errno::EINTR
|
|
* IO.select([serv])
|
|
* retry
|
|
* end
|
|
* # sock is an accepted socket.
|
|
*
|
|
* Refer to Socket#accept for the exceptions that may be thrown if the call
|
|
* to TCPServer#accept_nonblock fails.
|
|
*
|
|
* TCPServer#accept_nonblock may raise any error corresponding to accept(2) failure,
|
|
* including Errno::EWOULDBLOCK.
|
|
*
|
|
* If the exception is Errno::EWOULDBLOCK, Errno::AGAIN, Errno::ECONNABORTED, Errno::EPROTO,
|
|
* it is extended by IO::WaitReadable.
|
|
* So IO::WaitReadable can be used to rescue the exceptions for retrying accept_nonblock.
