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.
