when to fflush ?

[David Skeen]

The description of fseek() in the X/Open Portability Guide (issue 3)
says that "If the stream is writable and buffered data had not been
written to the underlying file, fseek() will cause the unwritten data
to be written to the file and mark the st_ctime and st_mtime fields of
the file for update."  I did a quick scan of POSIX 1003.1-1990, but
didn't find such an explicit statement.
