>The <A HREF="Network-Socket.html"

sockets. Essentially the entire C socket API is exposed through
this module; in general the operations follow the behaviour of the C
functions of the same name (consult your favourite Unix networking book).

>A higher level interface to networking operations is provided
through the module <A HREF="Network.html"
