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.

Syntax

int NSPLookupServiceEnd(
  HANDLE hLookup
);

Parameters

Return Value

The function should return NO_ERROR (zero) if the routine succeeds. It should return SOCKET_ERROR (-1) if the routine fails and it must set the appropriate error code using SetLastError.
