The openldap-software list is actually the most appropriate
list for discussing how to use OpenLDAP Software, including
APIs.  http://www.openldap.org/lists/
Please direct future posts appropriate.

You can manage your own event loop, but it's more difficult
to manage your own network input/output.  Use LDAP_OPT_DESC
to grab the socket description, use your own select(2) (or
poll(2)), and call ldap_result(3) in poll mode.

No.  It's an internal function and should not called directly.
