nng_msg_chop - remove data from end of message body
#include <nng/nng.h> int nng_msg_chop(nng_msg *msg, size_t size); int nng_msg_chop_u16(nng_msg *msg, uint16_t *val16); int nng_msg_chop_u32(nng_msg *msg, uint32_t *val32); 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.
