Use sizeof, it's even the default. You can also limit the amount of work done by using some value lower than sizeof if for example you only want the closest 3 items.

Well, I told him that it isn't recommended. I wrote something about sizeof too, but I deleted it afterwards, because that's not what he wants. sizeof only gets an array dimension size at compile time, but he wanted the number of IDs that will be filled in at run time (or maybe even more than that, if the array isn't big enough, maybe he wants the total nearby IDs without any array limit, which is what that function actually returns).

The downside of using strlen: it can report a wrong size if the whole array is filled up with IDs different than 0, so it won't find the internal 0 correctly. It may check too much causing some kind of buffer overflow.
