int ixp_dial(const char *address);
int ixp_announce(const char *address);
An address on which to connect or listen,
specified in the Plan 9 resources
These functions hide some of the ugliness of Berkely Sockets. ixp_dial connects to the resource at address, while ixp_announce begins listening on address.
These functions return file descriptors on success, and -1 on failure. ixp_errbuf(3) may be inspected on failure.
