- file name extension. Required this because NIST files use the same
- filename extension as Microsoft WAV files.
- * src/sndfile.c src/sndfile.h
- Added short, int and double read/write functions which work in frames rather
- than items. This was originally suggested by Maurizio Umberto Puxeddu

- Fixed default FORMsize in __aiff_open_write ().
- * src/sndfile.c

- Added call to ferror () in main header parsing loop of __XXX_open_read
- functions. This should fix problems on platforms (MacOS, AmigaOS) where
- fseek()ing or fread()ing beyond the end of the file puts the FILE*
- stream in an error state until clearerr() is called.
- * tests/write_read_test.c
- Added tests for RAW header-less PCM files.
- * src/common.h
- Moved definition of struct tribyte to pcm.c which is the only place
- which needs it.
