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.
