NAME

6       BIO_f_null - null filter
7

SYNOPSIS

9        #include <openssl/bio.h>
10
11        BIO_METHOD *   BIO_f_null(void);
12

DESCRIPTION

14       BIO_f_null() returns the null filter BIO method. This is a filter BIO
15       that does nothing.
16
17       All requests to a null filter BIO are passed through to the next BIO in
18       the chain: this means that a BIO chain containing a null filter BIO
19       behaves just as though the BIO was not there.
20

NOTES

22       As may be apparent a null filter BIO is not particularly useful.
23

RETURN VALUES

25       BIO_f_null() returns the null filter BIO method.
