NAME
nng_msg_header - return message header
SYNOPSIS
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.
