+.Sh DESCRIPTION
+.Fn BIO_f_null
+returns the null filter BIO method.
+This is a filter BIO that does nothing.
+.Pp
+All requests to a null filter BIO are passed through to the next BIO
+in the chain: this means that a BIO chain containing a null filter BIO
+behaves just as though the BIO was not there.
+.Sh NOTES
+As may be apparent, a null filter BIO is not particularly useful.
+.Sh RETURN VALUES
+.Fn BIO_f_null
+returns the null filter BIO method.
