Active Directory API

[myntv]

I am computer student and I have assignment to write simple console application in C/C++ that read current status of Active Directory. The teacher said some example of more complex utility is Active Directory Change Reporter. In my case I need only read the status and do not report changers. What API should be used to have access to Active Directory. Thank you in advance. The assignment deadline is March 15 2008. Please help.
Thank you

No such language called C/C++. Maybe your first order of business is figuring out which language to use.

Win32 API. See http://msdn2.microsoft.com/en-us/library/bb905319.aspx
