Transformations of pointer parameters in C

Hi,


I want to do a transformation of C-programs to eliminate some
pointers. As C has no reference parameters, they are often emulated
like this:


void add(int a, int b, int* c){
    *c = a + b;
}


main(){
    int z;
    add(1, 2, &z);
    ...
}


In my abstract syntax tree of that program I want to transform it into
an extended C with reference parameters. The example would look like
the following, which has a reference paramater notation similar to
C++:


void add(int a, int b, int& c){
    c = a + b;
}


main(){
    int z;
    add(1, 2, z);
    ...
}


Has anybody done something like that before? (Of course, you can think
of more complicated examples, where the actual argument is a
pointer...)
Any hint would be appreciated.


Thanks,
Jens
