Nah, I doubt it returns an errno for file not found, that's option C.

I think it might return -1 if there's an issue opening it.

Wait, what if the file is empty? Does that change anything?

It should return 0 since the file exists.

I feel like the errno value might come into play if the file didn't exist, but since it does exist, that shouldn't be the case here.

I remember a practice question where reading an empty file returned -1, but that was in a different context.

I think the code should return 0 since it's reading a zero-length file, but I'm not entirely sure.

I’m leaning towards option D, but I can't recall if reading a zero-length file would actually give a value like 2.

Wait, what's the difference between a registration handler and just-in-time provisioning? I'm not sure which one of those requirements I should focus on.

Okay, let's break this down. We have a multi-cloud Salesforce implementation with B2C Commerce, Service Cloud, and Marketing Cloud. The key is understanding how to best leverage the different environments for testing and deployment.
