The tags file doesn't always have line numbers in it. In many cases
(such as the Vim help tags files) it has a search command instead.
But what was Yakov asking? "I am moving the cursor, have I arrived at
the definition for tag foobar?" or "Is there a tag definition, and which
one, on the current cursor line?" ?
Here is what I'm asknig. I have tag name, X. I want to remap key C-]
so that it remembers tag name in some variable b:tag. The I want some other
mapping that will bring me to *next* definition of "last C-]ed" tag.
I thought the logic can be "check if we are already at some definition of
tag b:tag". If we are, then just to the next definition. But maybe it's not
needed, [to knwo whether we are at the definion", if the next-tag-def
mapping will remember the definition number. Yes, in fact that's all
that's needed. I think I have everything in palce to create the
next-tag-definition mappnig.

See my original reply to you: Vim already has "get to next/previous
matching tag", :tn[ext] and :tN[ext] / :tp[revious]
