SYNOPSIS

#include <nng/nng.h>

int nng_msg_chop(nng_msg *msg, size_t size);

int nng_msg_chop_u32(nng_msg *msg, uint32_t *val32);

DESCRIPTION

The nng_msg_chop() and nng_msg_chop_u32() functions remove data from the end of the body of message msg. The first function removes size bytes. The second function removes 4 bytes, and stores them in the value 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 body is too short to remove the requested data.
