=head1 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.

=head1 NOTES
|
|
|
|
|
|
|
|
|
|
As may be apparent a null filter BIO is not particularly useful.
