How to cancel and settle funds for a specific order atomically?

[Danilo-Araujo-Silva]

How can we cancel and settle the funds for just only one specific order at once? Preferably in an atomic method?

For example, we have this documentation here:
https://github.com/project-serum/serum-ts/tree/master/packages/serum

But we only have the option to cancel an order separately and then settle the funds for all of the orders for a market, with two API calls.

How can we do that using just one method that would guarantee to us that the order was canceled and the funds have returned?

Shouldn't it be either canceling or settling? In what way does it make sense to settle a canceled order?

Because if you cancel and do not settle the funds, your funds become locked, and you can't reuse it to place a new order.
So it would be better to have an option that cancel the order but automatically free the funds for reuse.

I see, that makes sense. I guess it might be possible to create a transaction with cancel and settle instructions then to achieve what you want.

Is there a way to see if there are 'locked' funds which need to be settled?
