NAME
nng_msg_chop - remove data from end of message body
SYNOPSIS
DESCRIPTION
The nng_msg_chop() family of functions removes data from
the end of the body 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 functions return 0 on success, and non-zero otherwise.
ERRORS
NNG_EINVAL
|
The message body is too short to remove the requested data. |
