#include <openssl/bio.h>

const BIO_METHOD *

() 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.

BIO_f_null() returns the null filter BIO method.


BIO_f_null() first appeared in SSLeay 0.8.0 and has been available since OpenBSD 2.4.
