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.

SEE ALSO

None.
