nng_msg_header(3)

SYNOPSIS

#include <nng/nng.h>

void *nng_msg_header(nng_msg *msg);

DESCRIPTION

The nng_msg_header() function returns a pointer to the start of the header content of the message msg.

The message header contains protocol-specific header content. Most applications should not need to access this content, but it is available for raw mode sockets (set with the NNG_OPT_RAW option.)
The value returned by this is invalidated by a call to any of the functions that modify the message or the header content.

RETURN VALUES

Pointer to start of message header.

ERRORS

None.
