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. 

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. 

NOTES

A null filter BIO is not particularly useful. 

RETURN VALUES

The BIO_f_null() function returns the null filter BIO method.
