The modules described in this chapter provide interfaces to operating
system features that are available on selected operating systems only.
The interfaces are generally modelled after the or C
interfaces but they are available on some other systems as well
(e.g. Windows or NT). Here's an overview:
- signal
- — Set handlers for asynchronous events.
- socket
- — Low-level networking interface.
- select
- — Wait for I/O completion on multiple streams.
- thread
- — Create multiple threads of control within one namespace.
