NAME

6       rpc_localaddr - discover local endpoint address for an RPC client
7

SYNOPSIS

9       int rpc_localaddr(struct rpc_clnt * clnt, struct sockaddr * buf,
10                         size_t buflen);
11

ARGUMENTS

13       clnt
14           RPC client structure
15
16       buf
17           target buffer
18
19       buflen
20           size of target buffer, in bytes
21

DESCRIPTION

23       Returns zero and fills in “buf” and “buflen” if successful; otherwise,
24       a negative errno is returned.
25
26       This works even if the underlying transport is not currently connected,
27       or if the upper layer never previously provided a source address.
28

THE RESULT OF THIS FUNCTION CALL IS TRANSIENT

30       multiple calls in succession may give different results, depending on
31       how local networking configuration changes over time.
