NAME
Coro::BDB - truly asynchronous bdb accessSYNOPSIS
use Coro::BDB; use BDB; # can now use any of the bdb requests
DESCRIPTION
This module is an AnyEvent user, you need to make sure that you use and run a supported event loop.This module implements a thin wrapper around the BDB module: Each BDB request that could block and doesn't get passed a callback will normally block all coroutines. after loading this module, this will no longer be the case (it provides a suitable sync prepare callback).
It will also register an AnyEvent watcher as soon as AnyEvent chooses an event loop.
The AnyEvent watcher can be disabled by executing "undef $Coro::BDB::WATCHER". Please notify the author of when and why you think this was necessary.
This module does not export anything (unlike Coro::AIO), as BDB already supports leaving out the callback. (Unfortunately, it ties a C context to each coroutine executing such a callback, so in the future, it might export more efficient wrappers).
