How to use an NSInteger in a c-style class declaration

I have a c-style class declaration:

#pragma once

class CSound
{
private:
   NSInteger bufferID;
public: 
    CSound(const char* fileName);
    ~CSound();
    static void init();
    void play();
};

The compiler says NSInteger does not name a type.

If I put the "NSInteger bufferID;" in the .mm file (not in the .h) it works. What am I doing wrong?

EDIT

As I still have no solution, I did a quick dirty-ugly-fix:

in .h file, in the class definition

void* pBufferID;

and in the .mm file

// constructor
pBufferID = new NSUInteger;

// destructor
delete (NSUInteger*)pBufferID;

// everywhere I use it
*((NSUInteger*)pBufferID)

Do you have the:

#import <UIKit/UIKit.h> (iOS) or

#import <Cocoa/Cocoa.h> (Mac OS)

..imported at the top of your .h file?

And are you sure you have all the frameworks linked to your project?

foundation.framework
appKit.framework
UIKit.framework

You're not including the header that defines NSInteger from your own header file (probably Foundation.h). Presumably you are doing so in your .mm file. Just move that #import or #include directive into your header.
