+POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/fscanf.html}
+
+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 9.
+@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
+On Windows, this function doesn't support the @code{hh}, @code{ll}, @code{j},
+@code{t}, @code{z} size specifiers.
