== NAME
nng_msg_append - append to message body
== SYNOPSIS
[source, c]
----
#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
[horizontal]
`NNG_ENOMEM`:: Insufficient free memory exists.
