.SH SYNOPSIS

.IX Header "SYNOPSIS"
|
|

\&

|
\& const BIO_METHOD *BIO_f_null(void);

.SH DESCRIPTION
|
|
.IX Header "DESCRIPTION"
|
|
\&\fBBIO_f_null()\fR 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
|
|
.IX Header "NOTES"
|
|
As may be apparent a null filter BIO is not particularly useful.
|
|
.SH "RETURN VALUES"
|
|
.IX Header "RETURN VALUES"
|
|
\&\fBBIO_f_null()\fR returns the null filter BIO method.
