Auto-generating C header file from C++ header?

[Bit byte]

I am having to provide a C interface to (quite a few) C++ classes.
Is there a way that I can automate this process?

example :

class X
{
public:

X();

void f();
};

will produce this C header :

// C interface

#ifdef __cplusplus
extern "C" {
#endif

// Type-safe, opaque pointer.
typedef struct C_X_* X_Handle;


X_Handle CreateX();
void DestroyX(X_Handle x);

void X_f(X_Handle x);

#ifdef __cplusplus
}
#endif


I can then (manually) implement this:

// C++ implementation

X_Handle CreateX()
{
return reinterpret_cast<X_Handle>(new X);
}

void DestroyX(X_Handle x)
{
delete reinterpret_cast<X*>(x);
}

void X_f(X_Handle x)
{
reinterpret_cast<X*>(x)->f();
}

Not that I know what can help you, but I'm just wondering how you would
translate private function, template, virtual function etc...

Seems to me a very complicated task Good luck!
