int nng_msg_chop_u64(nng_msg *msg, uint64_t *val64);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.
These functions return 0 on success, and non-zero otherwise.
NNG_EINVAL
|
The message body is too short to remove the requested data. |
