Hello Thanks for the explanation. I have doubt regarding the spawn. Can I use Spawn to launch the .exe file (.exe is a console application developed using the visual studio, which renders different shapes using openGL and transfer rendered data to the server and then server display this data on the browser ? ) Right now the issue I am facing is whenever I launch the .exe using spawn I am not able to render anything in openGL context.

where can we see the real application of child process in our software application?

@mafiacodes 3 жыл бұрын

Like for example ur making cmd line applications, or u want to exec some script on certain conditions, or if u want to train an ml model on different thread, or if u want to backup database. This db backup example is coming in a couple of days and u can see the real application

it should not, may try on a different machine, if there also you get an error, share your repo
