Subject: Win32 API Callbacks

I want to write a Windows network audio program in pure Ruby. However, 
this requires me to call an API function called waveInOpen which takes a 
callback function as one of its arguments.

The callback function looks like this:

void CALLBACK waveInProc(
  HWAVEIN hwi,
  UINT uMsg,
  DWORD dwInstance,
  DWORD dwParam1,
  DWORD dwParam2
);

Is it possible to achieve this in Ruby or do I have to write a wrapper 
DLL?


Thanks in advance
