Is this behavior guaranteed under POSIX?  Why are you using read()/write()?
I don't think you can mix buffered and unbuffered I/O and expect things
to function properly.  If you don't want to use fread()/fwrite() with
streams, than you probably should forget about using the other functions
and macros that deal with the stream structure (FILE).
