nng_msg_get_pipe - get pipe for message

       The nng_msg_get_pipe() returns the nng_pipe object associated with message msg. On receive, this is the
       pipe from which a message was received. On transmit, this would be the pipe that the message should be
       delivered to, if a specific peer is required.

           Note

           Not all protocols support overriding the destination pipe.

       The most usual use case for this is to obtain information about the peer from which the message was
       received. This can be used to provide different behaviors for different peers, such as a higher level of
       authentication for peers located on an untrusted network. The nng_pipe_getopt() function is useful in
       this situation.

       None.

       nng_msg_get_pipe - get pipe for message

       This function returns the pipe associated with this message, which will be a positive value. If the pipe
       is non-positive, then that indicates that no specific pipe is associated with the message.
