Proposed New /H option for cmd #34

Closed DaveBenham closed 4 years ago

This might be a stretch, but it would be nice for a child cmd process to pass heap values back to the parent. This would definitely be useful with pipes and FOR /F, and probably useful in general.

Perhaps it could be implemented by adding an /H:size option to cmd that would reserve size space in the parent heap, and then the child cmd would need a way of storing values in the reserved parent heap space. Ideally there would be overrun protection.

Perhaps this would need to be implemented via an call @cmd /h:size /c command extension so that the parent could parse the command and reserve the space before the actual cmd /h:address /c command was issued.

Or perhaps this is just a zany idea.

Carlos suggested something like that in email; I shot it down, not gonna happen.

There was the idea of provide something like interprocess communication (with events) but I think design that is related to provide async features, that will cause a lot of discussion.
