Package com.sun.jna.platform.win32
Interface Winsvc.Handler
- All Superinterfaces:
- AltCallingConvention,- Callback,- StdCall,- StdCallLibrary.StdCallCallback
- Enclosing interface:
- Winsvc
An application-defined callback function used with the
 RegisterServiceCtrlHandler function. A service program can use it as the
 control handler function of a particular service.
 
 This function has been superseded by the Winsvc.HandlerEx control
 handler function used with the
 Advapi32.RegisterServiceCtrlHandlerEx(java.lang.String, com.sun.jna.platform.win32.Winsvc.HandlerEx, com.sun.jna.Pointer)
 function. A service can use either control handler, but the new control
 handler supports user-defined context data and additional extended
 control codes.

This behavior changed starting with Windows Server 2003 and Windows XP with SP2.- 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.
