NAME
nng_msg_header_chop - remove data from end of message header
SYNOPSIS
DESCRIPTION
The nng_msg_header_chop() family of functions removes
data from the end of the header of message msg.
The first function removes size bytes.
The remaining functions remove 2, 4, or 8 bytes, and stores them in the value
(such as val32),
after converting them from network-byte order (big-endian) to native
byte order.
RETURN VALUES
These function return 0 on success, and non-zero otherwise.
ERRORS
NNG_EINVAL
|
The message header is too short to remove the requested data. |
