DOS return code

[whterbtobj]

How can I get the DOS return code when a process ended without waiting?

For example:

If I run format C:\
when format is completed it would return 0 if it was successful.

Can I use GetExitCodeProcess to get the return code?

Yepp that's the right way as far as I understand from MSDN. Make sure you wait for the process to terminate though

What if I dont want to wait?

What if I dont want to wait? Okay. You don't wait! Then what would you do of return value? There should be some usage of return value, if you need return value. May be you can put the call to command (via CreateProcess/ShellExecute), and wait for it to complete in a separate thread.

That makes sense. Creating a separate thread.

But can't I do something like this?

while (STILL_ALIVE)
{
//do other stuff


}
//the program has closed
//get the return code

You can. Just specify 0 as timeout for WaitForSingleObject.
