zmq_msg_copy(3) =============== NAME ---- zmq_msg_copy - copies content of a message to another message SYNOPSIS -------- 'int zmq_msg_copy (zmq_msg_t *dest, zmq_msg_t *src);' DESCRIPTION ----------- Copy the 'src' message to 'dest'. The original content of '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 'zmq_msg_size' and copy the data using 'memcpy'. RETURN VALUE ------------ In case of success the function returns zero. Otherwise it returns -1 and sets 'errno' to the appropriate value. ERRORS ------ No errors are defined. EXAMPLE ------- ---- zmq_msg_t dest; rc = zmq_msg_init (&dest); assert (rc == 0); rc = zmq_msg_copy (&dest, &src); assert (rc == 0); ---- SEE ALSO -------- linkzmq:zmq_msg_move[3] linkzmq:zmq_msg_init[3] linkzmq:zmq_msg_init_size[3] linkzmq:zmq_msg_init_data[3] linkzmq:zmq_msg_close[3] AUTHOR ------ Martin Sustrik
