  POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/freopen.html}
  
  Gnulib module: freopen
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  On some platforms, if @code{stream} does not already have an open
  file descriptor, @code{freopen} returns the stream without opening
  the file: glibc 2.24.
  @item
  On platforms where @code{off_t} is a 32-bit type, @code{freopen} may not work
  correctly with files larger than 2 GB.  (Cf. @code{AC_SYS_LARGEFILE}.)
  @item
  On Windows platforms (excluding Cygwin), this function does usually not
  recognize the @file{/dev/null} filename.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  On Windows platforms (excluding Cygwin), this function does not set @code{errno}
  upon failure.
  @item
  This function does not support a @code{NULL} file name argument on some
  platforms:
  OpenBSD 4.9, AIX 7.1, HP-UX 11.23, IRIX 6.5, OSF/1 5.1, Solaris 10, mingw, MSVC 14.
  @item
  This function does not fail when the file name argument ends in a slash
  and (without the slash) names a nonexistent file or a file that is not a
  directory, on some platforms:
  HP-UX 11.00, Solaris 9, Irix 5.3.
  @item
  Applications should not assume that @code{fileno(f)} will be the same
  before and after a call to @code{freopen(name,mode,f)}.  However, the
  module @code{freopen-safer} can at least protect @code{stdin}, @code{stdout},
  and @code{stderr}.
  @end itemize
