# zmq\_msg\_move(3)

move content of a message to another message

## NAME

zmq\_msg\_move - move content of a message to another message

## SYNOPSIS

**int zmq\_msg\_move (zmq\_msg\_t** *\*dest***, zmq\_msg\_t** *\*src***);**

## DESCRIPTION

The *zmq\_msg\_move()* function shall move the content of the message object referenced by *src* to the message object referenced by *dest*. No actual copying of message content is performed, *dest* is simply updated to reference the new content. *src* becomes an empty message after calling *zmq\_msg\_move()*. The original content of *dest*, if any, shall be released.

**Caution**\

Never access *zmq\_msg\_t* members directly, instead always use the *zmq\_msg* family of functions.

## RETURN VALUE

The *zmq\_msg\_move()* function shall return zero if successful. Otherwise it shall return -1 and set *errno* to one of the values defined below.

## ERRORS

**EFAULT**

Invalid message.
