=head1 SYNOPSIS |
| 6 |
|
|
|
| 7 |
|
|
use AnyEvent::BDB; |
| 8 |
|
|
use BDB; |
| 9 |
|
|
|
| 10 |
|
|
# can now use any of the requests your BDB module supports |
| 11 |
|
|
# as long as you use an event loop supported by AnyEvent. |

=head1 DESCRIPTION |
| 14 |
|
|
|
| 15 |
|
|
This module is an L<AnyEvent> user, you need to make sure that you use and |
| 16 |
|
|
run a supported event loop. |
| 17 |
|
|
|
| 18 |
|
|
Loading this module will install the necessary magic to seamlessly |
| 19 |
|
|
integrate L<BDB> into L<AnyEvent>, i.e. you no longer need to concern |
| 20 |
|
|
yourself with calling C<BDB::poll_cb> or any of that stuff (you still |
| 21 |
|
|
can, but this module will do it in case you don't). |
| 22 |
|
|
|
| 23 |
|
|
The AnyEvent watcher can be disabled by executing C<undef |
| 24 |
|
|
$AnyEvent::BDB::WATCHER>. Please notify the author of when and why you |
| 25 |
|
|
think this was necessary. |
