Please help with registry access

[made_of_asp]

Hello,

I am trying to convert Visual Basic Registry Access to C++ functions and i have a lot of errors about conversions but i have no idea how to fix them.

char* RegQueryStringValue (HKEY__* key, char* cValue)
{
ulong* iResult;
ulong* iValueType;
ulong iBuffSize;
unsigned char zBuff;

iResult = RegQueryValueEx (key, cValue, NULL, iValueType, &zBuff, iBuffSize);

//    if (iResult == 0){
//        if (iValueType == 1){
//            char zBuff[iBuffSize];            
//                iResult =  RegQueryValueEx (key, cValue, NULL, iValueType, &zBuff, iBuffSize);
//        }
//    }

}

char* GetSetting(HKEY__* key, char* cPath[], char* cValue[])
{
    //Read a setting from registry
    unsigned long int hKey;
    unsigned short int hDataType;
    char zBuff[256];

    RegOpenKey (key, cPath*, hKey);
    strcpy(zBuff, RegQueryStringValue (&hKey, cValue);
    RegCloseKey (hKey);
} 

I am a newbie to C++. Please help me.
Thanks,
