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

Note

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

Syntax

INT WSASetService(
  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 fields of the WSAQUERYSET (Bluetooth) structure that are associated with values in the SDP record.

Field Subfield 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

lpBlob

Points to a BTHNS_SETBLOB structure, containing information about the service to be added.

essOperation

 

RNRSERVICE_REGISTER.

dwControlFlags

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.

Field Subfield 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

lpBlob

BTHNS_SETBLOB structure, containing the service record handle.
