I have migrated from VS2010 to VS2017, and find that _spawnl is no longer supported.
I use _spawnl to launch additional instances of my code, and I save the handle that it returns so I can test if the process has finished or to kill it if necessary.
What feature do you recommend to use instead? I can use CreateProcessA(), but that does not return a handle. How do I get that?
Or is there another feature I should used?

Why do you not want to continue using _spawnl?
Are you changing your project to be a UWP?
CreateProcess returns the process handle via its lpProcessInformation parameter.
The Documentation does not seem to say that _spawnl is no longer supported.

Yes, I tried, and the return code was always an error.
But, no matter. I have managed to get CreateProcess() to work, so this problem is solved.
It did not. I switched to CreateProcess(), and it works now.
I don't know what UWP means. My program runs on Windows.
@Don Dilworth Did you try to build your project in VS2017 and actually experience a problem with _spawnl or are you just getting confused by the documentation you have read?
If you are talking about the same Windows desktop applications that you have previously asked questions about in the old MSDN forums (probably Synopsys) then _spawnl should continue to work for you.
I would love to keep using _spawnl(). But here is what is now the case:

This API cannot be used in applications that execute in the Windows Runtime. For more information, see CRT functions not supported in Universal Windows Platform apps.
So, are you converting your application to be a UWP one or not?
