NAME

       nng_msg - message

SYNOPSIS

           #include <nng/nng.h>

           typedef struct nng_msg nng_msg;

DESCRIPTION

       An nng_msg represents a single message sent between Scalability Protocols peers. Messages
       internally have a body, containing the application supplied payload, and a header,
       containing protocol specific routing and similar related information.

           Tip
           Using message-oriented functions is a good way to reduce the likelihood of data copies
           and improve application performance.

       Messages are allocated using the nng_msg_alloc() function, and are deallocated using the
       nng_msg_free() function.

       In addition there are other functions used to access message contents, including adding
       data to either the beginning or end of the message, automatic data conversion, and
       removing data from the beginning or end. These functions are designed to try to avoid
       copying message contents by making use of scratch areas at the beginning and end of the
       message.
