File I/O, Modular Programming

[rider eragon]

Hi all,

For those of you that don't know me, click on the link if you're interested: http://www.cplusplus.com/forum/general/38389/ .

Basically, today I'm trying to read from a binary file that contains an array of all the file names that need to be loaded.

Here's my code:

#include <iostream>
#include <Windows.h>
#include <fstream>
#include <string>
#include <vector>
#include "globals.h"
#pragma comment(lib, "user32.lib")

// Primitive Functions
...
void ReadBinaryFile(std::ifstream input, std::vector<char> files);

std::string fileName = "\\data\\allfiles.bin";
std::ifstream fileInput(fileName, std::ios::binary);
if (!fileInput)
{
	return 5; // The check files exist file is missing, so the game won't know what to load (hence the startup must fail).
}
else
{
	std::vector<char> files;
	ReadBinaryFile(fileInput, files);
	for (int i = 0; files[i] != '\0'; i++)
	{
		// Open all relevant files
	}
}

Here is ReadBinaryFile:

#include <iostream>
#include <fstream>
#include <vector>

void ReadBinaryFile(std::ifstream input, std::vector<char> files)
{
	input.read((char*)&files, sizeof files);
}

When I try to compile, I get the following error:

Error 1 error C2248: 'std::basic_ios<_Elem,_Traits>::basic_ios' : cannot access private member declared in class 'std::basic_ios<_Elem,_Traits>' c:\program files (x86)\microsoft visual studio 10.0\vc\include\fstream 890 1

If I get rid of my primitive function, I don't get this error, but obviously the program still won't compile. I need to have this function, as I'll be reading from an unknown amount of files (could be in the tens or the hundreds, depending on the player's preferences).

Also, as a side note, is DWORD a reserved data type in MS VC++ 2010? I got an error for the first time today saying: Error 1 error C2371: 'DWORD' : redefinition; different basic types c:\users\christopher\documents\visual studio 2010\projects\hangmanedu\hangmanedu\datatypes.h 13 1

for my typedef unsigned int DWORD;

Never before has this happened.
