thanks. after writing this letter i spotted unsafeUseAsCStringLen and
used it. now i'm curious about having these 4 functions:

useAsCString
useAsCStringLen
unsafeUseAsCString
unsafeUseAsCStringLen

and differences between their behavior. may be, it will be better to
keep only first two functions, with semantics already implemented
(with my patch) - `useAsCString` add zero byte while useAsCStringLen doesn't ?

i copy this letter to libraries list in hope that other FPS developers
may clear the question
