The shutdown method seems a suitable candidate, but a disconnect() method(which 
is semantically more correct) could be introduced.

[issue18095] unable to invoke socket.connect with AF_UNSPEC

2013-05-29 Thread Roman Valov 

New submission from Roman Valov:

There is a way to disconnect UDP socket
that was previously connected to specific
remote endpoint in C:

  struct sockaddr_in sin;
  memset((char *)sin, 0, sizeof(sin));
  sin.sin_family = AF_UNSPEC;
  connect(fd, (struct sockaddr *)sin, sizeof(sin));

However in this is not available in python, since connect
accepts only (host, port) as a parameter for UDP socket.

It's possible to drop port connection with port=0,
however I can't find a way to drop host connection.
