NAME

nng_msg_append - append to message body

SYNOPSIS

#include <nng/nng.h>

int nng_msg_append(nng_msg *msg, const void *val, size_t size);
int nng_msg_append_u16(nng_msg *msg, uint16_t val16);
int nng_msg_append_u32(nng_msg *msg, uint32_t val32);
int nng_msg_append_u64(nng_msg *msg, uint64_t val64);

DESCRIPTION

The nng_msg_append() family of functions appends data to the end of the body of message msg , reallocating it if necessary. The first function appends size bytes, copying them from val . The remaining functions append the value specified (such as val32 ) in network-byte order (big-endian).

RETURN VALUES

These functions return 0 on success, and non-zero otherwise.

ERRORS

NNG_ENOMEM

Insufficient free memory exists.
