I am curious to know what does the function open() in File returns. I know it is an integer, but of what? My guess is for error checking, but then, why not return Error instead?

Should be an Error which is an enumerated type. You can see in the code below it will return parameters invalid, can't open file, and OK.

The enum can be seen here:
