Looks good.

Part of me thinks you shouldn't have to specify environment in order to specify redirects, but I don't know how that works with the overloads. I know File is a struct, so it shouldn't bind to null, right?

No, there won't be any problem with adding overloads with and without environment, but then there'll be six spawnProcess() versions. We have to weigh that against the user having to explicitly specify a null when they don't want to add to the environment, but still want redirects. I don't know which is worse. I don't think this is too bad, though:

   auto p = spawnProcess("myapp", null, File("input.txt"));

OK, that is fine with me.

By "AA should be merged with the parent's environment or not, with the former being the default", I'm assuming the "set" flag will mean "don't inherit". What name do you have in mind? Since we already have dontDoTheCloseThing, I think dontDoTheEnvironmentInheritThing would be good ;)

I know it's bikeshedding, but negative flags are awful, we should come up with positive ones. ignoreParentEnv?

Now that the big pieces are seemingly falling into place, it is probably time for bikeshedding. I was thinking clearEnv or newEnv, but ignoreParentEnv is perhaps more explicit.

clearEnv is somewhat incorrect, since you could specify a new environment via the env parameter, it won't be clear. newEnv sounds ok, and probably is better than ignoreParentEnv to avoid a more verbose name, even if less descriptive. At the very least, it will make people look it up ;)


Speaking of negative flags, do you have better suggestions for the Config.noCloseStd... ones?

retainStdout

dontDoTheCloseThing became inheritFDs, btw. :) Also open for suggestions on that one.

That is fine with me.
