17. Interprocess Communication and Networking

The modules described in this chapter provide mechanisms for different processes to communicate.

Some modules only work for two processes that are on the same machine, e.g. signal and subprocess. Other modules support networking protocols that two or more processes can used to communicate across machines.

The list of modules described in this chapter is:

subprocess		Subprocess management.
socket		Low-level networking interface.
signal		Set handlers for asynchronous events.
popen2		Subprocesses with accessible standard I/O streams.
asyncore		A base class for developing asynchronous socket handling services.
asynchat		Support for asynchronous command/response protocols.
