EVENTINFO structure

This structure returns notifications about system state, sponsor processes, dependent processes, and shutdown notifications. The dwNotifyType field determines the meaning of the other fields.

Syntax

typedef struct _tag_event_info {
    DWORD dwNotifyType;
    DWORD dwLocation;
    DWORD dwProcessId;
} EVENTINFO;

Fields

dwNotifyType

Specifies one of the following Notification Types Received:

`TERMINATE`	This process is being terminated. The process must immediately clean up and exit.
`RTIO_CONSOLE_CLOSED`	The console window has been closed by the user (see Miscellaneous Configuration panel for details).
`DEPENDENT_REGISTERED`	A dependent registered against this sponsor process.
`DEPENDENT_UNREGISTERED`	A dependent unregistered against this sponsor process.
`DEPENDENT_TERMINATED`	A dependent of this sponsor process terminated without unregistering itself.
`SPONSOR_UNREGISTERED`	This sponsor process unregistered itself.
`SPONSOR_TERMINATED`	The sponsor of this dependent process terminated.
`RT_CLIENT_DOWN`	The real-time client is now offline.
`NT_HOST_DOWN`	The Windows host is now offline.
`RT_CLIENT_UP`	The real-time client is now active.
`NT_HOST_UP`	The Windows host is now active.
`NT_BLUESCREEN`	The local Windows host had a bluescreen error. When a bluescreen occurs, Windows is not allowed to run so that RT applications can continue. If you would like Windows to continue shutting down, you can use the RtContinueWindowsShutdown API.
`NT_HOST_SHUTDOWN_PENDING`	The Windows host shutdown is imminent. You can block Windows shutdown by calling RtShutdownBlockReasonCreate. Once you have finished cleanup, you can call RtShutdownBlockReasonDestroy.
`KERNEL_SHUTDOWN_PENDING`	This message is sent before a node is stopped. There is a configurable delay (default 500 ms) before the KERNEL_STOPPING message is sent and the node is stopped.
`KERNEL_STOPPING`	The kernel will stop shortly.
`NT_HOST_HIBERNATE`	The Windows Host is going into a hibernate state and the kernel will be stopped.
`NT_HOST_STANDBY`	The Windows Host is going into a standby state and the kernel will be stopped.

dwLocation

Reserved for future use. Always returns 0 (zero).

dwProcessId

Specifies the process identifier of the process that has registered/unregistered or terminated.
