Thread: This stupid binary dll isnt working...

First off im a total newbie when it comes to C++, but i was making a binary functions dll in C++ and well it only returns '0' back to me.

Code:

//Define export macro
#define export extern "C" __declspec( dllexport )

//Headers
#include <iostream>
#include <fstream>
#include <windows.h>
using namespace std;

ifstream::pos_type size; //Size of file
char * memblock; //Memory "Storage"
char * pEnd; //End char
double ret; //Variable helps with conversion

export double readFile(PCHAR filepath)
{
       ifstream file (filepath, ios::in|ios::binary|ios::ate);
       if (file.is_open())
       {
                          size = file.tellg();
                          memblock = new char [size];
                          file.seekg (0, ios::beg);
                          file.read (memblock, size);
                          file.close();
                          
                          ret = strtod(memblock,&pEnd); //Damnit! Now to convert :(
                          return ret; //Return PLEASE! lol
       }else{
             return 0;
       }
}

The program i use ONLY accepts double and null arguments to be passed back and forth through the dll, so i had to convert the file's binary data into 'double' but like i said i only get '0' in return...

So can anyone help with this? Im pretty sure its the dll thats causing the problem, but im not sure.

Thanks,
-Steve
