  @section @code{fflush}
  @findex fflush
  
  POSIX specification:@* @url{https://pubs.opengroup.org/onlinepubs/9699919799/functions/fflush.html}
  
  Gnulib module: fflush
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  @code{fflush} followed by @code{fseek} or @code{fseeko}, applied to an input
  stream, should have the effect of positioning the underlying file descriptor.
  It doesn't do this on some platforms:
  glibc 2.34, FreeBSD 13.0, and others.
  @item
  @code{fflush} on an input stream changes the position of the stream to the
  end of the previous buffer, on some platforms: mingw, MSVC 14.
  @item
  @code{fflush} on an input stream right after @code{ungetc} does not discard
  the @code{ungetc} buffer, on some platforms:
  macOS 11.1, FreeBSD 6.0, NetBSD 9.0, OpenBSD 6.7, Cygwin 1.5.25-10.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  @code{fflush}, @code{ftell}, @code{ftello}, @code{fgetpos} behave incorrectly
  on input streams that are opened in @code{O_TEXT} mode and whose contents
  contains Unix line terminators (LF), on some platforms: mingw, MSVC 14.
  @item
  On Windows platforms (excluding Cygwin), this function does not set @code{errno}
  upon failure.
  @item
  This function crashes if the stream's file descriptor has already been
  closed, if @code{MSVC_INVALID_PARAMETER_HANDLING} is
  @code{HAIRY_LIBRARY_HANDLING} or @code{SANE_LIBRARY_HANDLING},
  on some platforms:
  MSVC 14.
  @item
  @code{fflush} on an input stream right after @code{ungetc} does not discard
  the @code{ungetc} buffer, on some platforms:
  AIX 5.1, HP-UX 11, IRIX 6.5, Solaris 11 2010-11, mingw, MSVC 14.
  @end itemize
