+On Windows platforms (excluding Cygwin), the descriptors returned by
+the @code{accept} function can not be used in calls to @code{read},
+@code{write}, and @code{close}; you have to use @code{recv}, @code{send},
+@code{closesocket} in these cases instead.

+On Windows platforms (excluding Cygwin), error codes for @code{accept}
