| 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.
|
|---|

|
|---|
| 28 | BIO_f_null() returns the null filter BIO method.
