NAME
nng_msg_header_trim - remove data from start of message header
SYNOPSIS
DESCRIPTION
The nng_msg_header_trim() family of functions remove
data from the start of the header of message msg.
The first function removes size bytes.
The remaining functions removes 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
This function returns 0 on success, and non-zero otherwise.
ERRORS
NNG_EINVAL
|
The message header is too short to remove the requested data. |
