I'm wanting to write a client in C/C++ that does a "refresh and persist" sync search on an entry. I'm looking at the ldap_sync(3) man page and that looks like it would do most things that I need. I can't find any example code that is using that interface, so if somebody could point me to any that does, I'd really appreciate it.

I do understand that I need to initialize the API with the ldap_sync_initialize() to get an ldap_sync_t structure. The members of the structure seem straightforward enough but I don't understand how I connect my ldap connection (LDAP*) to this API. How does that work??

Also, I don't understand how the different function typedefs work. I mean that I understand that I need four functions:

ldap_sync_search_entry_f my_search_entry(...); ldap_sync_search_reference_function_f my_search_reference(...); ldap_sync_search_intermediate_f my_search_intermediate(...); ldap_sync_search_result_f my_search_result(...);

But how does the ldap_sync(3) API become aware of those functions?

Or... is there an easier way to do what I want? Looks like the ldapsearch command line tool just adds a control to the search (-E sync=rp) and handles the resulting messages as necessary. Should I be trying to do that instead of using ldap_sync(3)?

Thanks,
