NSPLookupServiceEnd (Compact 2013)
3/26/2014
This function is called to free the handle after previous calls to NSPLookupServiceBegin and NSPLookupServiceNext.
It is possible to receive an NSPLookupServiceEnd call on another thread while processing an NSPLookupServiceNext. This indicates that the client has canceled the request and the provider should close the handle and return from the NSPLookupServiceNext call as well, setting the last error to WSA_E_CANCELLED.

HANDLE hLookup
);
