WSALookupServiceBegin (Bluetooth)

  • Article

This function initiates a client query that is constrained by the information contained within a WSAQUERYSET (Bluetooth) structure. This function returns a handle that is used by the WSALookupServiceNext (Bluetooth) function.

Note   This function is actually a Winsock function. However, the information that is presented in it is specific to Bluetooth.

INT WSALookupServiceBegin(
  LPWSAQUERYSET pQuerySet,
  DWORD dwFlags,
  LPHANDLE lphLookup
);

Parameters

  • pQuerySet
    [in] Pointer to the search criteria.
  • dwFlags
    [in] The following table shows a list of flags for this parameter.
    Flag Description
    LUP_CONTAINERS Specifies that device discovery is to be performed. If this flag is not set, service discovery will be performed instead.
    LUP_RES_SERVICE Searches the local SDP database. Clear this flag to search for services on a peer device.
  • lphLookup
    [out] Handle to be used when calling the WSALookupServiceNext (Bluetooth) function to start retrieving the results set.

Return Values

None.

Remarks

If LUP_CONTAINERS is set, SDP performs a device inquiry to find other Bluetooth devices in the area. This function performs the query. The WSALookupServiceNext function retrieves the results one device at a time.

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.

Requirements

OS Versions: Windows CE .NET 4.0 and later.
Header: Bt_api.h.
Link Library: Btdrt.lib.
