+.TH zmq_msg_copy 3 "" "(c)2007-2009 FastMQ Inc." "0MQ User Manuals"
+.SH NAME
+zmq_msg_copy \- copies content of a message to another message
+.SH SYNOPSIS
+.B int zmq_msg_copy (zmq_msg_t *dest, zmq_msg_t *src);
+.SH DESCRIPTION
+Copy the
+.IR src
+message to
+.IR dest .
+The original content of
+.IR dest
+is orderly deallocated.
+Caution: The implementation may choose not to physically copy the data, rather
+to share the buffer between two messages. Thus avoid modifying message data
+after the message was copied. Doing so can modify multiple message instances.
+If what you need is actual hard copy, allocate new message using
+.IR zmq_msg_size
+and copy the data using
+.IR memcpy .
+.SH RETURN VALUE
+In case of success the function returns zero. Otherwise it returns -1 and
+sets
+.IR errno
+to the appropriate value.
+.SH ERRORS
+No errors are defined.
+.SH EXAMPLE
+.nf
+zmq_msg_t dest;
+rc = zmq_msg_init (&dest);
+assert (rc == 0);
+rc = zmq_msg_copy (&dest, &src);
+assert (rc == 0);
