rpc_localaddr – discover local endpoint address for an RPC client
Synopsis
int rpc_localaddr(struct rpc_clnt *clnt, struct sockaddr *buf, size_t buflen);Arguments
clnt
-
- RPC client structure
buf
- target buffer
buflen
- size of target buffer, in bytes
Description
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.
