Kurt, I am new to socket programming. I will review and get back to you.

I am trying to allow a second application to send a STOP command to MPD, using the existing local socket created by MPD. I would like to allow a form of Convenience Switching. So if music is playing through MPD from an MPD client (JRiver). The second application could then STOP MPD play safely(as though command came from MPD client (Jriver). I have attached a terminal screen shot below, showing mpd socket assignment.A snippet I wrote recently: static int connect_uri(const char *host, int port, int preferred_type) { int sock; if (*host == '@' || *host == '/') { /* unix socket */ struct sockaddr_un addr = { .sun_family = AF_UNIX, }; int socklen; strcpy(addr.sun_path, host); socklen = strlen(host) + offsetof(struct sockaddr_un, sun_path); sock = socket(AF_UNIX, preferred_type, 0); if (sock < 0) mylog(LOG_ERR, "socket AF_UNIX ...: %s", ESTR(errno)); if (connect(sock, (void *)&addr, socklen) < 0) mylog(LOG_ERR, "bind %s: %s", host, ESTR(errno)); return sock; } The remainder goes via ip sockets, which is not necessarily what you want. Is this what you were looking for? Kurt
