I want to make an app that reads GPU Voltage thru Riva

As said in the title... I want to make an app that reads GPU Voltage thru Riva.

Here's my test-app:

Code:

#include <windows.h>
#include <iostream>
#include "RivaTunerExports.h"
using namespace std;

READ_I2C_EX_PROC ReadI2CEx = NULL;
GET_HOST_APP_VERSION_PROC GetHostAppVersion = NULL;
GET_I2C_BUS_NUM_EX_PROC GetI2CBusNumEx = NULL;

int main(int argc, char**argv) {
	HMODULE hRiva = LoadLibrary("C:\\Program Files (x86)\\RivaTuner v2.24\\RivaTuner.exe");
	if(hRiva)
		cout << "RivaTuner successfully found and loaded." << endl;
	GetHostAppVersion = (GET_HOST_APP_VERSION_PROC)GetProcAddress(hRiva, "GetHostAppVersion");
	GetI2CBusNumEx = (GET_I2C_BUS_NUM_EX_PROC)GetProcAddress(hRiva, "GetI2CBusNumEx");
	ReadI2CEx = (READ_I2C_EX_PROC)GetProcAddress(hRiva, "ReadI2CEx");
	if(!(GetHostAppVersion && GetI2CBusNumEx && ReadI2CEx)) {
		cout << "Error locating function pointers" << endl;
		return 1;
	}
	cout << "Version: " << GetHostAppVersion() << endl;
	BYTE test = NULL;
	if(ReadI2CEx(0, 0x01, 0x70, 0x18, &test))
		cout << "Data: " << (int*)test << endl;
	else
		cout << "FAIL" << endl;
	return 0;
}

Any way to get this to work (without turning it into a DLL plugin)? Currently, it crashes upon reaching the call to the ReadI2CEx function.

As I said, it's a test-app, so I did not code a GUI for it just yet, so I'm using Win32 Console.

 

So I'll have to resort to attaching to the process?
