BIO_f_null(3)                OpenSSL                BIO_f_null(3)

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.
