  Gnulib module: stdio, nonblocking
  
  Portability problems fixed by Gnulib module @code{stdio}, together with module @code{nonblocking}:
  @itemize
  @item
  This function crashes when invoked with invalid arguments on some platforms:
  MSVC 14.
  @item
  When reading from a non-blocking pipe whose buffer is empty, this function
  fails with @code{errno} being set to @code{EINVAL} instead of @code{EAGAIN} on
  some platforms:
  mingw, MSVC 14.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  This function may fail with error @code{EINTR}, even in programs that don't
  install any signal handlers, on some platforms:
  Mac OS X 10.5.
  @end itemize
  
  For handling @code{EINTR}, Gnulib provides a module @samp{safe-read} with a
  function @code{safe_read}.
