|BIO_F_NULL(3)||Library Functions Manual||BIO_F_NULL(3)|
BIO_f_null — null
returns the null filter BIO method. This is a filter BIO that does nothing.
As may be apparent, a null filter BIO is not particularly useful.
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.
BIO_f_null() returns the null filter BIO
