|This function is actually a Winsock function. However, the information that is presented in it is specific to Bluetooth.|
If the operation was successful, the return value is zero. Otherwise, the value SOCKET_ERROR is returned. You can retrieve the specific error number by calling the WSAGetLastError function.
To cancel a pending inquiry, pass BTHNS_ABORT_CURRENT_INQUIRY as a handle parameter to WSALookupServiceEnd (Bluetooth).
If you call WSALookupServiceEnd from another thread while an existing WSALookupServiceNext (Bluetooth) is executing, the call to WSALookupServiceNext will be canceled and will return to the calling application immediately.
