Link a member function directly to C method declared in a header

Question

Can I link a member function like this in some way? redeclaring the method as a member and get it call the Mmsystem.h method to not have to wrap it?

#include <windows.h>
#include <Mmsystem.h>

  namespace SoundLib {

 public class CWave
 {
 public:
  // WaveIn call
  external UINT waveOutGetNumDevs(VOID);
 };

}

Answer 1

Sorry, no, you can't.

Answer 2

No, you have to wrap it. Additionally, your code has some errors, such as external versus extern (though that was theoretical anyway) and public before your class.

Answer 3

No, but you can wrap it with inline and even static and hope that compiler is smart enough (which it likely is).

class CWave {
public:
    static inline UINT waveOutGetNumDevs(void) { return ::waveOutGetNumDevs(); }
};

Answer 4

You will need to explicitly call the function you wrapped:

class CWave
{
public:
    static UINT waveOutGetNumDevs(VOID)
    {
        return ::waveOutGetNumDevs();
    }
};

Note the double colon. Since your method and the global function have the same name, you need the double colon to prevent infinite recursion.
