200.SH "DESCRIPTION"
201\fIBIO_f_null()\fR returns the null filter BIO method. This is a filter BIO
202that does nothing.
203.PP
204All requests to a null filter BIO are passed through to the next BIO in
205the chain: this means that a BIO chain containing a null filter BIO
206behaves just as though the BIO was not there.
207.SH "NOTES"
208As may be apparent a null filter BIO is not particularly useful.
209.SH "RETURN VALUES"
210\fIBIO_f_null()\fR returns the null filter BIO method.
