SQL Identity Column

I read Daniel Cruikshank's article in the Centerfield Newsletter about
identity columns and would like to use them as suggested as a primary
key but was puzzled as to how you determine what value the system
assigned. In researching it a bit, I found the IDENTITY_VAL_LOCAL()
function.

However, I can't see that there is any guarantee that the value returned
is from the insert that was just done by my job as opposed to an insert
done by another job. How do I know that another job didn't sneak in an
insert after mine and just before the function returns a value?
