Name
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.
