/**
 * @file   vfer_test_server.c
 * @author Ivan Beschastnikh
 * @brief  Test: A listening, always accepting server
 *
 * This test tests the server.c functionality and the associated api
 * in api.c to set up a listening socket, start listening on the
 * socket and accept incoming connections over that socket. This
 * server is a daemon, so it never stops listening and it never closes
 * any of its accepted or listening [one] sockets. It does not read
 * from the sockets.

 * -     07/30/05        ivan            Added to the CVS tree (old test_server.c retired)
