BIO_F_NULL(3) OpenSSL BIO_F_NULL(3)NAMEBIO_f_null - null filter
BIO_METHOD * BIO_f_null(void);
DESCRIPTIONBIO_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.
As may be apparent a null filter BIO is not particularly useful.
RETURN VALUESBIO_f_null() returns the null filter BIO method.
