* @api LONG | DriverProc | The entry point for an installable driver.
*
* @parm DWORD | dwDriverId | For most messages, <p dwDriverId> is the DWORD
* value that the driver returns in response to a <m DRV_OPEN> message.
* Each time that the driver is opened, through the <f DrvOpen> API,
* the driver receives a <m DRV_OPEN> message and can return an
* arbitrary, non-zero value. The installable driver interface
* saves this value and returns a unique driver handle to the
* application. Whenever the application sends a message to the
* driver using the driver handle, the interface routes the message
* to this entry point and passes the corresponding <p dwDriverId>.
* This mechanism allows the driver to use the same or different
* identifiers for multiple opens but ensures that driver handles
* are unique at the application interface layer.
*
* The following messages are not related to a particular open
* instance of the driver. For these messages, the dwDriverId
* will always be zero.
*
* DRV_LOAD, DRV_FREE, DRV_ENABLE, DRV_DISABLE, DRV_OPEN
*
* @parm HANDLE | hDriver | This is the handle returned to the
* application by the driver interface.
*
* @parm WORD | wMessage | The requested action to be performed. Message
* values below <m DRV_RESERVED> are used for globally defined messages.
* Message values from <m DRV_RESERVED> to <m DRV_USER> are used for
* defined driver protocols. Messages above <m DRV_USER> are used
* for driver specific messages.
*
* @parm LONG | lParam1 | Data for this message. Defined separately for
* each message
