0x00000005 Notifies a service that the system is shutting down so the service can perform cleanup tasks.
If a service accepts this control code, it must stop after it performs its cleanup tasks and return NO_ERROR. After the SCM sends this control code, it will not send other control codes to the service. SERVICE_CONTROL_STOP
0x00000001 Notifies a service that it should stop.
If a service accepts this control code, it must stop upon receipt and return NO_ERROR. After the SCM sends this control code, it does not send other control codes.
Windows XP: If the service returns NO_ERROR and continues to run, it continues to receive control codes. This behavior changed starting with Windows Server 2003 and Windows XP with SP2.
*
* This parameter can also be one of the following extended control codes. Note that these control codes are not supported by the {@link Handler} function.
*
*
* Control code Meaning SERVICE_CONTROL_DEVICEEVENT
0x0000000B Notifies a service of device events. (The service must have registered to receive these notifications using the RegisterDeviceNotification function.) The dwEventType and lpEventData parameters contain additional information. SERVICE_CONTROL_HARDWAREPROFILECHANGE
0x0000000C Notifies a service that the computer's hardware profile has changed. The dwEventType parameter contains additional information. SERVICE_CONTROL_POWEREVENT
0x0000000D Notifies a service of system power events. The dwEventType parameter contains additional information. If dwEventType is PBT_POWERSETTINGCHANGE, the lpEventData parameter also contains additional information. SERVICE_CONTROL_SESSIONCHANGE
0x0000000E Notifies a service of session change events. Note that a service will only be notified of a user logon if it is fully loaded before the logon attempt is made. The dwEventType and lpEventData parameters contain additional information. SERVICE_CONTROL_TIMECHANGE
0x00000010 Notifies a service that the system time has changed. The lpEventData parameter contains additional information. The dwEventType parameter is not used.
Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP: This control code is not supported. SERVICE_CONTROL_TRIGGEREVENT
0x00000020 Notifies a service registered for a service trigger event that the event has occurred.
Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP: This control code is not supported. SERVICE_CONTROL_USERMODEREBOOT
0x00000040 Notifies a service that the user has initiated a reboot.
Windows Server 2008 R2, Windows 7, Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP: This control code is not supported.
*
* This parameter can also be a user-defined control code, as described in the following table.
*
*
* Control code Meaning Range 128 to 255. The service defines the action associated with the control code.
*
* @param dwEventType The type of event that has occurred. This
* parameter is used if dwControl is
* SERVICE_CONTROL_DEVICEEVENT,
* SERVICE_CONTROL_HARDWAREPROFILECHANGE,
* SERVICE_CONTROL_POWEREVENT, or
* SERVICE_CONTROL_SESSIONCHANGE. Otherwise, it is
* zero.
*
* If dwControl is SERVICE_CONTROL_DEVICEEVENT, this parameter can be
* one of the following values:
*
*
* - DBT_DEVICEARRIVAL
* - DBT_DEVICEREMOVECOMPLETE
* - DBT_DEVICEQUERYREMOVE
* - DBT_DEVICEQUERYREMOVEFAILED
* - DBT_DEVICEREMOVEPENDING DBT_CUSTOMEVENT
*
*
* If dwControl is SERVICE_CONTROL_HARDWAREPROFILECHANGE, this parameter
* can be one of the following values:
*
*
* - DBT_CONFIGCHANGED
* - DBT_QUERYCHANGECONFIG
* - DBT_CONFIGCHANGECANCELED
*
*
* If dwControl is SERVICE_CONTROL_POWEREVENT, this parameter can be one
* of the values specified in the wParam parameter of the
* WM_POWERBROADCAST message.
*
* If dwControl is SERVICE_CONTROL_SESSIONCHANGE, this parameter can be
* one of the values specified in the wParam parameter of the
* WM_WTSSESSION_CHANGE message.
*
* @param lpEventData [in] Additional device information, if required.
* The format of this data depends on the value of
* the dwControl and dwEventType parameters.
*
* If dwControl is SERVICE_CONTROL_DEVICEEVENT, this data corresponds to
* the lParam parameter that applications receive as part of a
* WM_DEVICECHANGE message.
*
* If dwControl is SERVICE_CONTROL_POWEREVENT and dwEventType is
* PBT_POWERSETTINGCHANGE, this data is a pointer to a
* POWERBROADCAST_SETTING structure.
*
* If dwControl is SERVICE_CONTROL_SESSIONCHANGE, this parameter is a
* pointer to a WTSSESSION_NOTIFICATION structure.
*
* If dwControl is SERVICE_CONTROL_TIMECHANGE, this data is a pointer to
* a SERVICE_TIMECHANGE_INFO structure.
*
* @param lpContext [in] User-defined data passed from
* {@link com.sun.jna.platform.win32.Advapi32#RegisterServiceCtrlHandlerEx}. When multiple
* services share a process, the lpContext parameter
* can help identify the service.
*
* @return The return value for this function depends on the control
* code received.
*
* The following list identifies the rules for this return value:
*
*
* - In general, if your service does not handle the control, return
* ERROR_CALL_NOT_IMPLEMENTED. However, your service should return
* NO_ERROR for SERVICE_CONTROL_INTERROGATE even if your service does
* not handle it.
* - If your service handles SERVICE_CONTROL_STOP or
* SERVICE_CONTROL_SHUTDOWN, return NO_ERROR.
* - If your service handles SERVICE_CONTROL_DEVICEEVENT, return
* NO_ERROR to grant the request and an error code to deny the
* request.
* - If your service handles SERVICE_CONTROL_HARDWAREPROFILECHANGE,
* return NO_ERROR to grant the request and an error code to deny the
* request.
- If your service handles
* SERVICE_CONTROL_POWEREVENT, return NO_ERROR to grant the request and
* an error code to deny the request.
* - For all other control codes your service handles, return
* NO_ERROR.
*
