| 4 | ||
| e117a890 | 5 | BIO_f_null - null filter |
| 5fd0cd9a DSH |
6 | |
| 7 | =head1 SYNOPSIS | |
| 8 | ||
| 9 | #include <openssl/bio.h> | |
| 10 | ||
| e9b77246 | 11 | const BIO_METHOD *BIO_f_null(void); |

| 13 | =head1 DESCRIPTION | |
| 14 | ||
| 15 | BIO_f_null() returns the null filter BIO method. This is a filter BIO | |
| 16 | that does nothing. | |
| 17 | ||
| 18 | All requests to a null filter BIO are passed through to the next BIO in | |
| 19 | the chain: this means that a BIO chain containing a null filter BIO | |
| 20 | behaves just as though the BIO was not there. | |
| 21 | ||
| 22 | =head1 NOTES | |
| 23 | ||
| 24 | As may be apparent a null filter BIO is not particularly useful. | |
| 25 | ||
| 26 | =head1 RETURN VALUES | |
| 27 | ||
| 28 | BIO_f_null() returns the null filter BIO method. | |
