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