Well, it doesn't seem to expose anything other than the set of chosen functions (read / write / seek etc) -- no data structure, no special #include's... My problem is that the VIO API isn't (yet) clearly specified / documented (e.g. what the virtual read / write should return for errors, for EOF, whether it's acceptable to return short counts). You may also be missing an errno-like VIO function, but I can't comment much as I don't quite understand the existing sf_error() stuff. By "fragile" you probably mean that the set of VIO functions, or their API, might change in the future? Do you foresee the need to add or remove stuff? It seems like a pretty standard set of functions, similar to what you'd specify for a VFS layer. > I would be surprised if reset-by-seek didn't work on standard > WAV/AIFF etc files with PCM data accessed via the standard > sf_read/write* functions. Probably, but since I'm using sndfile, I don't want to special-case formats in my app... At the very least, does a successful sf_seek() guarantee that all errors have been cleared and that future I/O will occur undisturbed (in the places where the file contains no errors, obviously)? -- Dan _______________________________________________ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev
