		142	Perl on Win32 supports only ASCII filenames (the reason is that it abuses
		143	an internal flag to store wether a filename is Unicode or ANSI, but that
		144	flag is used for somethign else in the perl core, so there is no way to
		145	detect wether a filename is ANSI or Unicode-encoded). The BDB module
		146	tries to work around this issue by assuming that the filename is an ANSI
		147	filename and BDB was built for unicode support.

162		174
		175	The C<SV *callback> is the optional callback function to call when the
		176	request is completed. This last callback argument is special: the callback
		177	is simply the last argument passed. If there are "optional" arguments
		178	before the callback they can be left out. The callback itself can be left
		179	out or specified as C<undef>, in which case the function will be executed
		180	synchronously.
		181
		182	For example, C<db_env_txn_checkpoint> usually is called with all integer
		183	arguments zero. These can be left out, so all of these specify a call
		184	to C<< DB_ENV->txn_checkpoint >>, to be executed asynchronously with a
		185	callback to be called:
		186
		187	db_env_txn_checkpoint $db_env, 0, 0, 0, sub { };
		188	db_env_txn_checkpoint $db_env, 0, 0, sub { };
		189	db_env_txn_checkpoint $db_env, sub { };
		190
		191	While these all specify a call to C<< DB_ENV->txn_checkpoint >> to be
		192	executed synchronously:
		193
		194	db_env_txn_checkpoint $db_env, 0, 0, 0, undef;
		195	db_env_txn_checkpoint $db_env, 0, 0, 0;

601	callback has been called. The default implementation works like this:	713	is called to wait until the first callback has been called (it must set
		714	C<$!> to the return status).
		715
		716	This mechanism can be used to include BDB into other event mechanisms,
		717	such as L<Coro::BDB>.
		718
		719	To allow other, callback-based, events to be executed while callback-less
		720	ones are run, you could use this sync prepare function:
602		721
603	sub {	722	sub {
604	my $status;	723	my $status;
605	(	724	(
606	sub { $status = $! },	725	sub { $status = $! },
607	sub { BDB::poll while !defined $status; $! = $status },	726	sub { BDB::poll while !defined $status; $! = $status },
608	)	727	)
609	}	728	}
610		729
		730	It works by polling for results till the request has finished and then
		731	sets C<$!> to the return value. This means that if you don't use a
		732	callback, BDB would simply fall back to synchronous operations.
		733
		734	By default, or if the sync prepare function is set to C<undef>, is to
		735	execute callback-less BDB requests in the foreground thread, setting C<$!>
		736	to the return value, without polling for other events.
