  LPWSAQUERYSET pQuerySet,
  DWORD dwFlags,
  LPHANDLE lphLookup
);

pQuerySet

Flag Description

LUP_CONTAINERS

lphLookup

[out] Handle to be used when calling the WSALookupServiceNext (Bluetooth) function to start retrieving the results set.

You can specify extra parameters for device inquiries by having the lpsqRestriction->IpBlob point to a BTHNS_INQUIRYBLOB structure.

If LUP_CONTAINERS is not set, an SDP service search is performed. The lpsqRestrictions->IpBlob must point to a BTHNS_RESTRICTIONBLOB data structure.
