| 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. |
