-.TH zmq_msg_copy 3 "" "(c)2007-2010 iMatix Corporation" "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);
