get a region list

Subject: get a region list

Hi, trying the following code results in datasize = 0 and removing the if(){} results in a regions array (null). It is checking this property on a playing AudioFileID which had a region already set to it. Am I using this correctly?

Mike

OSStatus result;

UInt32 dataSize;

result = AudioFileGetPropertyInfo (fAudioFile, kAudioFilePropertyRegionList, &dataSize, NULL);

NSLog(@"regionlist datasize %d", dataSize);

if (result == noErr)

{

CFArrayRef regions = NULL;

result = AudioFileGetProperty(fAudioFile, kAudioFilePropertyRegionList, &dataSize, &regions);

NSLog(@"regions array %@", (NSArray *)regions);

}
