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