I'm tring to create a simple VM, and one of the things I wanted to do was to use an array of function pointers. Using the opp-codes as indexes to the proper functions should be more efficient than using a massive switch statement to find the right function. My problem is somewhere with the function pointers. Here is the compiler error I'm getting: error C2064: term does not evaluate to a function taking 2 arguments For simlpicity, I have not included the complete program, but have re-written a snippet that shows how I did it, and gives the same error: First the header Then the source Finally the shell I'm using MS VC++.net (2003) Any help would be appreciated
//cTest.h
#ifndef CTEST_H
#define CTEST_H
#include <stdio.h>
class cTest
{
public:
void run(); //called from outside
private:
void foo(int a, int b); //This a function that I want to run
void (cTest::*pFoo)(int a, int b); //This is a function pointer, with the same arguments as the function
}; //cTest
#endif
//cTest.cpp
//Implementation of cTest.h
#include "cTest.h"
// This is the function we're trying to get to
void cTest::foo(int a, int b)
{
printf("%d %d\n",a,b); //Just enough to see if it works
} //foo
//Called from outside
void cTest::run()
{
pFoo = foo; //Point the function pointer to the actual function
pFoo(1,2); //Now try to execute the function
//I've also tried the following:
//pFoo=&cTest::foo;
//cTest::pFoo(1,2);
} //run
// main.cpp
#include "cTest.h"
void main() //program entry
{
cTest TEST;
TEST.run();
} //main
