I'm getting :

java.lang.IllegalArgumentException: Callback argument class [I requires custom type conversion

Here is the C code:

typedef void (__cdecl* KMEXT_FPMONITORINGVUMETER)( void *pContext, ULONG *pPeaks, DWORD dwChannels, LONGLONG llTimestamp );

Here is my Java declaration of the callback:

public static interface KMEXT_FPMONITORINGVUMETER extends Callback { void callback(Pointer pContext, int [] pPeaks, int dwChannels, long llTimestamp); }

The dwChannels parameter tells me the number of 32-bit ints to expect starting at the address in pPeaks. I could also use a Buffer type instead of an int array, I suppose.. but I think I will still have the problem of dealing with the size of the buffer.

What is the best practice in this situation?

Thanks in advance,

Scott
