141 BIO_f_null \- null filter
143 .IX Header "SYNOPSIS"
145 \& #include <openssl/bio.h>
147 \& BIO_METHOD * BIO_f_null(void);
150 .IX Header "DESCRIPTION"
151 \&\fIBIO_f_null()\fR returns the null filter \s-1BIO\s0 method. This is a filter \s-1BIO\s0
154 All requests to a null filter \s-1BIO\s0 are passed through to the next \s-1BIO\s0 in
155 the chain: this means that a \s-1BIO\s0 chain containing a null filter \s-1BIO\s0
156 behaves just as though the \s-1BIO\s0 was not there.
159 As may be apparent a null filter \s-1BIO\s0 is not particularly useful.
161 .IX Header "RETURN VALUES"
162 \&\fIBIO_f_null()\fR returns the null filter \s-1BIO\s0 method.
