Hum... Why?

Is the error code wrong and should be ERROR_FILE_NOT_FOUND? And then,
why setting this other error code?
Or is the error code right, and then, what's the purpose of such comment?
Or do you have a doubt about the right error code to use? Be it one or
the other?

I come back to my eternal comment: don't comment for yourself. Comment
for the others, you're not alone here. So, make it explicit.

Cheers,
