Re: [asio-users] basic_socket::close() - all scheduled operations are cancelled immediately?

[Alejandro S. <al...@gm...>]

The correct definition should be "as soon as possible" or "any time soon".

Christopher might enlight you in the correct direction.

Here was some discussion about the subject:
http://sourceforge.net/mailarchive/forum.php?thread_id=29777152&forum_id=42787

It isn't simple to enforce the end of all asyncronous calls. The close
is also more or less asynchronous, since this library is calles ASIO
=)

Cheers,
Alejandro.
