From 8783aa8ea57c3a6989e0722d5184e98d543352d4 Mon Sep 17 00:00:00 2001 From: Andrew Tridgell Date: Wed, 19 Jan 2005 03:20:20 +0000 Subject: r4831: added udp support to our generic sockets library. I decided to incorporate the udp support into the socket_ipv4.c backend (and later in socket_ipv6.c) rather than doing a separate backend, as so much of the code is shareable. Basically this adds a socket_sendto() and a socket_recvfrom() call and not much all. For udp servers, I decided to keep the call as socket_listen(), even though dgram servers don't actually call listen(). This keeps the API consistent. I also added a simple local sockets testsuite in smbtorture, LOCAL-SOCKET (This used to be commit 9f12a45a05c5c447fb4ec18c8dd28f70e90e32a5) --- source4/torture/local/socket.c | 134 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 134 insertions(+) create mode 100644 source4/torture/local/socket.c (limited to 'source4/torture/local/socket.c') diff --git a/source4/torture/local/socket.c b/source4/torture/local/socket.c new file mode 100644 index 0000000000..cdd379e934 --- /dev/null +++ b/source4/torture/local/socket.c @@ -0,0 +1,134 @@ +/* + Unix SMB/CIFS implementation. + + local testing of socket routines. + + Copyright (C) Andrew Tridgell 2005 + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
