+# nng_msg_pipe
+
+## NAME
+
+nng_msg_pipe --- set or get pipe for message
+
+## SYNOPSIS
+
+```c
+#include <nng/nng.h>
+
+nng_pipe nng_msg_get_pipe(nng_msg *msg);
+void nng_msg_get_pipe(nng_msg *msg, nng_pipe p);
+```
+
+## DESCRIPTION
+
+The {{i:`nng_msg_set_pipe`}} function sets the [pipe][pipe] associated with [message][msg] _m_ to _p_.
+This is most often useful when used with protocols that support directing
+a message to a specific peer.
+For example the [_PAIR_][pair] version 1 protocol can do
+this when `NNG_OPT_PAIR1_POLY` mode is set.
+
+The {{i:`nng_msg_get_pipe`}} function returns the pipe that was previously set on the message _m_,
+either directly by the application, or when the message was received by the protocol.
+
+> [!NOTE]
+> Not all protocols support overriding the destination pipe.
+
+## RETURN VALUES
+
+The `nng_msg_get_pipe` function returns the pipe for the message _m_.
