/** \defgroup socket socket: General socket manipulations
\par Calling Convention
When calling a socket function, the socket file descriptor (where
required) will always be the first parameter. Functions that return a
file descriptor (either creating a new socket or accepting a connection
on a socket return that file descriptor on success or \c -1 on error.
All other functions return non-zero (true) on success or \c 0 (false) on
error. All functions set errno on error.
