[Tinyos-help] missing address-of operator?

[Flemming Nyboe]

Hello,

Is this legal:
--- 8< ----
serial_header_t* getHeader(message_t* msg) {
  return (serial_header_t*)(msg->data - sizeof(serial_header_t));
}
--- 8< ----
... or is the (msg->data) missing an address-of operator?
The construct is found (at least) in TEP111 and CC2420TimeSyncMessageP.ncf
