I want to debug my cgi script (C++) from IDE, so I would like to create a "debug mode": read file from disk, push it to own stdin, set some environment variables, that correspond this file and run the rest of the script as it was called by the web server. Is it possible and if it is, then how can I do that?

推荐答案

您不能推送到自己的stdin"，但是可以将文件重定向到您自己的stdin.

You can't "push to own stdin", but you can redirect a file to your own stdin.

freopen("myfile.txt","r",stdin);
