  Gnulib module: ioctl
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  On Windows platforms (excluding Cygwin), @code{ioctl} is called
  @code{ioctlsocket}, and error codes from this function are not placed in
  @code{errno}, and @code{WSAGetLastError} must be used instead.
  @item
  The second parameter is of type @code{unsigned long} rather than @code{int}
  on some platforms:
  glibc 2.26, Mac OS X 10.5, FreeBSD 11.0, NetBSD 7.0, OpenBSD 6.0, BeOS, Haiku 2017.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  Most @code{ioctl} requests are platform and hardware specific.
