1. You need an allocation whenever you cross heap boundaries (i.e. pass
an unmanaged string to a managed environment). This goes deeper than the
specific GC implementation: by definition, a GC may not touch unmanaged
memory.
2. Most modern environments work on unicode rather than ASCII, which
involves an allocation *and* a translation.
I am sorry, but using strcmp just to check a boolean flag is bad API
design (not to mention inefficient, idiomatic and unportable). It might
be me, but I really cannot see what advantage you think it confers over
a plain boolean query.
