328 * rpcb_v4_register - set or unset a port registration with the local rpcbind
329 * @program: RPC program number of service to (un)register
330 * @version: RPC version number of service to (un)register
331 * @address: address family, IP address, and port to (un)register
332 * @netid: netid of transport protocol to (un)register
333 * @result: result code from rpcbind RPC call
334 *
335 * RPC services invoke this function to advertise their contact
336 * information via the system's rpcbind daemon. RPC services
337 * invoke this function once for each [program, version, address,
338 * netid] tuple they wish to advertise.
339 *
340 * Callers may also unregister RPC services that are no longer
341 * available by setting the port number in the passed-in address
342 * to zero. Callers pass a netid of "" to unregister all
343 * transport netids associated with [program, version, address].
344 *
345 * Returns zero if the registration request was dispatched
346 * successfully and a reply was received. The rpcbind daemon's
347 * result code is stored in *result.
348 *
349 * Returns an errno value and sets *result to zero if there was
350 * some problem that prevented the rpcbind request from being
351 * dispatched, or if the rpcbind daemon did not respond within
352 * the timeout.
353 *
354 * This function uses rpcbind protocol version 4 to contact the
355 * local rpcbind daemon. The local rpcbind daemon must support
356 * version 4 of the rpcbind protocol in order for these functions
357 * to register a service successfully.
358 *
359 * Supported netids include "udp" and "tcp" for UDP and TCP over
360 * IPv4, and "udp6" and "tcp6" for UDP and TCP over IPv6,
361 * respectively.
362 *
363 * The contents of @address determine the address family and the
364 * port to be registered. The usual practice is to pass INADDR_ANY
365 * as the raw address, but specifying a non-zero address is also
366 * supported by this API if the caller wishes to advertise an RPC
367 * service on a specific network interface.
368 *
369 * Note that passing in INADDR_ANY does not create the same service
370 * registration as IN6ADDR_ANY. The former advertises an RPC
371 * service on any IPv4 address, but not on IPv6. The latter
372 * advertises the service on all IPv4 and IPv6 addresses.
