Sorry this post is a little vague, but when my FSOUND_STREAMCALLBACK function returns, my application crashes at memory address 0x00000063.
-
I am using FSOUND_Stream_SetEndCallback to set the callback.
-
We have a custom memory manager, but when turned off, the crash still occurs.
-
I am using Microsoft Visual Studio .NET 2003.
-
The build uses the Multi-Threaded Debug option. (/MTd)
I don’t know if any of that is important, but please feel free to inquire about any of the other options as well. The stream plays fine. It’s just that when it ends, the callback is called, and then I get this weird crash.
If anyone knows what might be causing this, I’d appreciate your advice or ideas.

What FMOD/other functions are you calling in your endcallback?

Sounds like the callback function has the wrong calling convention.

class FModAudioMgr
{
static signed char FModStreamCallback( FSOUND_STREAM *stream, void *buff, int len, int param)
{
return 1;
}
};
…
FSOUND_Stream_SetEndCallback(newStreamingP,
reinterpret_cast<FSOUND_STREAMCALLBACK> (FModAudioMgr::FModStreamCallback), 0);
That’s how I set everything up.

As I said, it’s the wrong calling convention. You’ll need F_CALLBACKAPI in that declaration.
static signed char F_CALLBACKAPI FModStreamCallback( FSOUND_STREAM *stream, void *buff, int len, int param);

Been there, done that with the Delphi conversion.

Thanks Sly – you were exactly right. I used F_API as a test, and that worked too. I don’t think F_CALLBACKAPI is specified as being necessary with the function in the documentation (at least not in the FSOUND_STREAMCALLBACK specification). Maybe I missed something, but perhaps it should be included there.
Thanks again.
