Hello everybody, I'm trying to drive a WIN32 application from a Racket gui app to provide the QA guys a simple way to interact with it. So far I'm quite successful but I'm having a little issue. I spawn my subprocess with subprocess : https://docs.racket-lang.org/reference/subprocess.html And for the sake of completeness I want to know when suprocess failed (because the users tampered with the exe, because there's an ACL issue, whatever). The function doesn't have a return value for failure and it doesn't raise an exception when I do stuff like (subprocess "no exe here") or (subprocess "nice picture of an aardvark.png") It only returns a seemingly valid value.
Can someone help me ? Is it an API defect and a special value should be returned ? Should an exception be raised ? The doc doesn't say much about this. I don't really care about the OS-level cause of the failure but I need to know if it failed. I didn't test on my Linux box for consistency. By the way, subprocess-pid returns 0 on such a "never spawned" process, and I think it should be an error case too. Cheers, Bertrand PS: Here's the reddit thread where I asked how to do it: https://www.reddit.com/r/Racket/comments/f0cbrp/is_there_a_way_to_catch_subprocess_failures/ -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
