The functions you are looking for are getsockname and inet_ntop.

`code` struct sockaddr_in addr; size_t addr_len = sizeof(addr); if (getsockname(socketfd, (struct sockaddr *) &addr, (socklen_t *) &addr_len) < 0) { ERROR_PRINT("Error getting local address"); return NULL; } return inet_ntoa(addr.sin_addr);`code` – RafaelLopes Nov 21 '11 at 19:58

As a sidenote, `getpeername` gets the address of the _peer_, i.e. the remote end-point. `getsockname` gets the address of the local end-point. – Some programmer dude Nov 21 '11 at 13:22
