Hi All, I have what I think is a ZFS related bug. Unfortunately my simplest test case is a bit cumbersome and I haven't definitively proven that the problem is ZFS related. I'm hoping for some feedback on how to move forward. Quick background: I rip my CD's using grip and produce flac files. I tag the music using Musicbrainz' Picard and transcode it to mp3's within Picard

...32 API function calls. These function calls return the sound samples in an array of characters. My assumption is that this array of characters represents pairs of bytes that make up a short integer. I'm using the following code to convert the samples: LPTSTR *lpSaveBuffer; ...... for(j=0;j<nBytes;++J) { BYTE a = lpSaveBuffer[2*j]; // left byte BYTE b = lpSaveBuffer[2*j + 1]; // right byte short sample = (a << 8) | (b & 0xff); } I'm getting garbage as a result of this conversion. Any help would be appreciated. Thanks, Peter -------------- next part -------...
