| =head1 NAME | |
| BIO_f_null - null filter | |
| =head1 SYNOPSIS | |
| #include <openssl/bio.h> | |
| BIO_METHOD * BIO_f_null(void); | |
| =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. | |
| =head1 RETURN VALUES | |
| BIO_f_null() returns the null filter BIO method. | |
