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

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