Well, you haven't given us a lot here.  I take it you're trying to call functions in the other files with pointer parameters?

//File1.h
void Fun1(void * Param);

//File2.h
void Fun1(void * Param);

//File1.cpp
#include "File1.h"
void Fun1(void * Param){
  //Do something here with the parameter
}


//File2.cpp
#include "File2.h"
void Fun2(void * Param){
  //Do something here with the parameter
}

//Main.cpp
#include "File1.h"
#include "File2.h"
int main(){
  int *p_I;
  int j;
  char p_C[100];

  //do something

  Fun1(p_C);

  Fun2(p_I);

  Fun2(&j);
}
