-Gnulib module: ---
+Gnulib module: stdio, nonblocking
 
-Portability problems fixed by Gnulib:
+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 9.
+@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 9.

 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}.
