== NAME

nng_msg_set_pipe - set pipe for message

== SYNOPSIS

[source, c]
----
#include <nng/nng.h>

void nng_msg_set_pipe(nng_msg *msg, nng_pipe p);
----

== DESCRIPTION

The `nng_msg_set_pipe()` sets the pipe associated with message _m_ to _p_.
This is most often useful when used with protocols that support directing
a message to a specific peer.
For example the xref:nng_pair.7.adoc[_pair_] version 1 protocol can do
this when `NNG_OPT_PAIR1_POLY` mode is set.

NOTE: Not all protocols support overriding the destination pipe.

== RETURN VALUES

None.

== ERRORS

None.
