  Gnulib module: stdio, nonblocking
  
  Portability problems fixed by Gnulib module @code{stdio}, together with module @code{nonblocking}:
  @itemize
  @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
  C99 and POSIX.1-2001 and later require end-of-file to be sticky, that
  is, they require this function to act as if it reads end-of-file if
  @code{feof} would return nonzero.  However, on some systems this
  function attempts to read from the underlying file descriptor even if
  the stream's end-of-file indicator is set.  These systems include
  glibc and default Solaris.
  @item
  On Windows platforms (excluding Cygwin), this function does not set @code{errno}
  upon failure.
  @item
  On Windows, this function doesn't support the @code{hh}, @code{ll}, @code{j},
  @code{t}, @code{z} size specifiers.
  @end itemize
