NAME

       xs_msg_copy - copy content of a message to another message

SYNOPSIS

       int xs_msg_copy (xs_msg_t *dest, xs_msg_t *src);

DESCRIPTION

       The xs_msg_copy() function shall copy the message object referenced by src to the message
       object referenced by dest. The original content of dest, if any, shall be released.

           Caution
           The implementation may choose not to physically copy the message content, rather to
           share the underlying buffer between src and dest. Avoid modifying message content
           after a message has been copied with xs_msg_copy(), doing so can result in undefined
           behaviour. If what you need is an actual hard copy, allocate a new message using
           xs_msg_init_size() and copy the message content using memcpy().

           Caution
           Never access xs_msg_t members directly, instead always use the xs_msg family of
           functions.

RETURN VALUE

       The xs_msg_copy() 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.
