BIO_F_NULL(3)			    OpenSSL			 BIO_F_NULL(3)

NAME
       BIO_f_null - null filter

SYNOPSIS
	#include <openssl/bio.h>

	const 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
       As may be apparent a null filter	BIO is not particularly	useful.

RETURN VALUES
       BIO_f_null() returns the	null filter BIO	method.
