Create a Job object And terminate Child Process

JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE flag
How to gracefully handle when main.exe terminated, child.exe terminated also?
You need to use jobs. Main executable should create a job object, then you'll need to set JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE flag to your job object.
