RegisterApplicationRestart 重启进程api 注意事项

若要注册要重启的应用程序，请调用 RegisterApplicationRestart 函数。 Windows 错误报告 (WER) 如果应用程序至少运行了 60 秒，然后才无响应或遇到未经处理的异常，则会重启应用程序。

Wait at least 60 seconds before crashing, so this process becomes eligible for restart.

Module Name:

	AppRestart.c

Abstract:

	This sample demonstrates how to use the RegisterApplicationRestart API.

	The RegisterApplicationRestart API lets Windows Error Reporting restart the application automatically
	in the event that the application crashes or hangs, or has to be restarted due to an update.

	In this sample, we register the application for restart. We tell WER to restart the application with the
	"/restarted" command-line. This way the application can do custom processing when it is restarted.

	A process is eligible for automatic restart only if it had been running for longer than 60 seconds.
	This is done to prevent cyclical restarts.

	You may also choose to combine automatic application restart with application recovery, as shown in the
	AppRecovery sample.
