18. 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 mmap. Other modules support networking protocols
that two or more processes can use to communicate across machines.
The list of modules described in this chapter is:
- 18.1.
socket— Low-level networking interface - 18.2.
ssl— TLS/SSL wrapper for socket objects - 18.3.
