long zapp_GetUID();
-1 if an error occurs, and otherwise a signed integer of value 0 or greater.
Each call to zapp_GetUID increments an internal counter in L3DT, such that subsequent calls are guaranteed to receive a unique value that is greater than all previous values, up until wraparound occurs at circa 2 billion.
