BIO_f_null
NAME
Synopsis
236
BIO_f_null – null filter
#include
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.
SEE ALSO
None.
