Function pointers are possible in nesc. Here is an example:
typedef uint8_t (*fnptr_t)(uint8_t a, uint8_t b);
uint8_t adder(uint8_t a, uint8_t b) {
return a+b;
}
fnptr_t fnptr;
command result_t StdControl.start() {
fnptr = adder;
}
// every time the timer fires, add 3 to x
event result_t Timer.fired() {
x = fnptr(x, 3);
}
- om_p

You might be out of luck with the function pointers, I seem to
remember someone saying that they aren't used in nesc...try
searching this list and the nesc doc for some background.
Data pointers should be fine, although there are some tricks to
including C files. There was a discussion in march under the subject:
"c-written subroutines" that you may be able to search out as well.
I'm pretty fuzzy on it myself...
