How does file descriptor passing work. From what I can tell it uses the sendmsg and recvmsg calls. Is this only process to process over a non ip socket on the same machine (what's the right terminology for this, just a plain FIFO?), or could one conceivably pass a file descriptor over an ip socket?
File descriptors can only be passed over AF_UNIX sockets. These are like fancy FIFO's on the local host using the socket APIs for the communication and synchronization. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
