All sockets do - well, almost all; it is possible for a socket to exist without any process having a file descriptor referring to it, but it's rare. (The only examples I know of are sockets in transit in SCM_RIGHTS messages, when the sender has closed its descriptor and the receiver hasn't received it yet, and a few kernel-internal uses such as the NFS client.) /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
