SYNOPSIS

+
+

int zmq_msg_copy (zmq_msg_t *dest, zmq_msg_t *src);

+
+

DESCRIPTION

+
+

The zmq_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 +zmq_msg_copy(), doing so can result in undefined behaviour. If what you need +is an actual hard copy, allocate a new message using zmq_msg_init_size() and +copy the message content using memcpy().
+
+
+ + + +
+
Caution
+		Never access zmq_msg_t members directly, instead always use the +zmq_msg family of functions.
+
+
+

RETURN VALUE

+
+

The zmq_msg_copy() function shall return zero if successful. Otherwise it +shall return -1 and set errno to one of the values defined below.

+
+

ERRORS

+
+

No errors are defined.
