BthNsSetService

Other versions of this page are also available for the following:

• Windows Embedded CE 6.0 R3

8/28/2008

This function adds, updates, or removes service records from the local SDP database.

Note

To preserve Win32 compatibility, consider using the Winsock equivalent of this function. This function is equivalent to WSASetService.

Syntax

INT BthNsSetService(
  LPWSAQUERYSET lpqsRegInfo,
  WSAESETSERVICEOP essoperation,
  DWORD dwControlFlags
);

Parameters

• lpqsRegInfo
  [in] Pointer to the service information for registration or deregistration.

• essoperation
  [in] Value that is to be set to RNRSERVICE_REGISTER.

• dwControlFlags
  [in] Flag that is to be set to zero.

Return Value

If the operation is successful, the return value is zero (ERROR_SUCCESS). Otherwise, the value SOCKET_ERROR is returned. The following table shows possible error codes for the last error, if SOCKET_ERROR is set.

Error code	Description
WSASERVICE_NOT_FOUND	SDP is not running.
WSAEINVAL	The parameter is invalid.
WSA_NOT_ENOUGH_MEMORY	Memory is insufficient.

Remarks

Servers use this function to register specific service information with SDP. The following table shows the members of the WSAQUERYSET structure that are associated with values in the SDP record.

Member	Submember	Description
lpqsRegInfo	dwSize	sizeof(WSAQUERYSET)
	lpszServiceInstanceName	Not supported on Windows Embedded CE. Set to 0.
	lpServiceClassId	Not supported on Windows Embedded CE. Set to 0.
	dwNameSpace	NS_BTH.
	dwNumberOfCsAddrs	Not supported on Windows Embedded CE. Set to 0.
	IpcsaBuffer	Not supported on Windows Embedded CE. Set to 0.
	lpBlob	Points to a BTHNS_SETBLOB structure, containing information about the service to be added.
	*	All other WSAQUERYSET members are ignored.
essOperation		RNRSERVICE_REGISTER.
dwControlFlags		Equal to 0 (clear).

This function can be used to update an existing SD record with new information. The parameters of the call are the same as in the initial record registration. The following table shows the exceptions.

Member	Submember	Description
lpqsRegInfo	lpBlob	BTHNS_SETBLOB structure, containing the service record handle. The service record handle is a critical piece of data. Any differences between the existing SD record and the passed in SD record will be applied to match the passed in record. Attributes could be added, changed, or deleted, so long as the resulting record is legal according to SDP. Changes that could result in an invalid record cause this function to return an error. If an error is returned, the existing SDP record remains unchanged.

This function can be used to delete existing SDP records. The following table shows the fields of the WSAQUERYSET structure.

Field	Subfield	Description
lpqsRegInfo	dwSize	sizeof(WSAQUERYSET)
	dwNameSpace	NS_BTH
	lpBlob	BTHNS_SETBLOB structure, containing the service record handle
	*	All other fields are ignored
essOperation		RNRSERVICE_DELETE
dwControlFlags		0 (clear)

Requirements

Header	bt_api.h
Library	Btdrt.lib
