RPC_LOCALADDR(9) Linux Networking RPC_LOCALADDR(9)

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

struct rpc_clnt * clnt

RPC client structure

struct sockaddr * buf

target buffer

size_t 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.
