But when my program finish with some crash, or killed with

when program finish? I another works, how can I make plink.exe
only lives when program is running?
IMHO, your d program cannot have direct control over a spawned
process. However, I suggest a road map for you, although I am not
sure if it works.
- I don't know if d has something like C's expect [1] library,
but you will need a similar thing. Basically, It spawns processes
and handles their stdout. Maybe you can just wrap libexpect in D.
- Assuming you have "expect" running in D, you can spawn
"tasklist" [2] and somehow filter out (I recall that it can be
done with expect using a struct like a regex on stdout) its
stdout to determine the PID number [2] of the process that you
want to kill at the end of the program.
- then, in your main:
void main(){
...
scope(exit){ // maybe you should also be aware of
scope(success) and scope(failure)
killPlink(); // spawn another process: "Taskkill /PID
26356 /F"
}
...
}
