socket_strerror() takes as its errno parameter the return value of one of the socket functions, and returns the corresponding explanatory text. This makes it a bit more pleasant to figure out why something didn't work; for instance, instead of having to track down a system include file to find out what '-111' means, you just pass it to socket_strerror(), and it tells you what happened.
See also socket_accept(), socket_bind(), socket_connect(), socket_listen(), socket_create(), and socket_get_status().
