WvUnixConn Class Reference

#include <wvunixsocket.h>

Inheritance diagram for WvUnixConn:

WvFdStream WvStream WvErrorBase IObject

List of all members.

Detailed Description

WvStream-based Unix domain socket connection class.

Unlike WvTCPConn, WvUnixConn makes connections synchronously because either the remote server is there, or it isn't. For convenience, we'll just ignore situations where it's a local server but still slow.

FIXME: support SOCK_DGRAM mode somehow. This is a bit tricky since the listener/connection separation doesn't make as much sense then. I guess we could just ignore the listener or something...

FIXME: use the weird credential-passing stuff to exchange pid, uid, and gid with the remote end of the socket. See the unix(7) man page. This would be very cool for authentication purposes.
