The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.

Null terminated or not, the string compare is done only with the shortest string which is not null-terminated (the literal *right* part of the comparison)
No, the return value of a straightforward call to C's `getenv` is a
POINTER. It's not even some bytes that represent characters, plus a
null byte. It's the *address* of those bytes.
My point is that $str is futile and useless in this case
So, one of the crucial aspects of %STR is that it takes a pointer as
input. You need to handle that pointer somehow. %STR is a very
convenient way to do that, and in fact was designed EXACTLY for this
kind of thing.
