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.
