rpc_localaddr — discover local endpoint address for an RPC client
int rpc_localaddr ( | struct rpc_clnt * clnt, |
| struct sockaddr * buf, | |
size_t buflen); |
struct rpc_clnt * clntRPC client structure
struct sockaddr * buftarget buffer
size_t buflensize of target buffer, in bytes
Returns zero and fills in “buf” and “buflen” if successful; otherwise, a negative errno is returned.
This works even if the underlying transport is not currently connected, or if the upper layer never previously provided a source address.
The result of this function call is transient: multiple calls in succession may give different results, depending on how local networking configuration changes over time.
