NAME
BIO_f_null —
null filter
SYNOPSIS
#include
<openssl/bio.h>
BIO_METHOD *
BIO_f_null(void);
DESCRIPTION
BIO_f_null()
returns the null filter BIO method. This is a filter BIO that does nothing.
As may be apparent, a null filter BIO is not particularly useful.
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.
RETURN VALUES
BIO_f_null() returns the null filter BIO
method.
