Greetings again,
I'm now wondering if I SHOULD make the function in my previous email
handle the errors. The problem is...
I've probably missed something really obvious, but I'm trying to figure
out if there's any way to return more than one value from a function.
In particular this is relevant when I'm trying to return an error code
along with another integer or something.
What if say, I have a function that returns an integer, but if there's
an error, the function says to return null. Does that actually make
any sense? Or is that breaking something, or whatever?
Any thoughts on this matter would be most appreciated.
Cheers!
David.
