i everyone,

Sorry for asking a newbie's question, but I did not find any documentation or example on the web about the use of AudioFileOpenWithCallbacks.

I only need to write data : should I need to provide a AudioFile_ReadProc, AudioFile_GetSizeProc, AudioFile_SetSizeProc?

What should I pass as argument for void *inRefCon?

Here's an example : I've got an input procedure :

OSStatus InputProc(void *inRefCon,
						AudioUnitRenderActionFlags *ioActionFlags,
						const AudioTimeStamp *inTimeStamp,
						UInt32 inBusNumber,
						UInt32 inNumberFrames,
						AudioBufferList * ioData)
{
    OSStatus err =noErr;

	err= AudioUnitRender(theInputUnit,
						 ioActionFlags,
						 inTimeStamp,
						 inBusNumber,		//will be '1' for input data
						 inNumberFrames,	//# of frames requested
						 theInputBufferList);

    return err;
}

My file type is theType, and my file id is theFileID.

How should look the call to AudioFileOpenWithCallbacks?

Thanks for any help.

Simon
