* call-seq:
|
||||
* unixserver.accept_nonblock([options]) => unixsocket
|
||||
*
|
||||
* Accepts an incoming connection using accept(2) after
|
||||
* O_NONBLOCK is set for the underlying file descriptor.
|
||||
* It returns an accepted UNIXSocket for the incoming connection.
|
||||
*
|
||||
* === Example
|
||||
* require 'socket'
|
||||
* serv = UNIXServer.new("/tmp/sock")
|
||||
* 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 UNIXServer#accept_nonblock fails.
|
||||
*
|
||||
* UNIXServer#accept_nonblock may raise any error corresponding to accept(2) failure,
|
||||
* including Errno::EWOULDBLOCK.
|
||||
*
|
||||
* If the exception is Errno::EWOULDBLOCK, Errno::EAGAIN, Errno::ECONNABORTED or Errno::EPROTO,
|
||||
* it is extended by IO::WaitReadable.
|
||||
* So IO::WaitReadable can be used to rescue the exceptions for retrying accept_nonblock.
|
||||
*
|
||||
* By specifying `exception: false`, the options hash allows you to indicate
|
||||
* that accept_nonblock should not raise an IO::WaitReadable exception, but
|
||||
* return the symbol :wait_readable instead.
|
||||
*
|
||||
* === See
|
||||
* * UNIXServer#accept
|
||||
* * Socket#accept
