Generic pointers are always stored using three bytes. By default C function pass up to three parameters in registers and further parameters are passed in fixed memory locations. Keil Setup For The fixed memory locations used for parameters passing may be in internal data memory or external data memory depending upon the memory model used.

As we already discussed, Keil C is not much different from a normal C program.
