Kudos for the library design - it looks quite nice. We're looking for a safe, cross-platform, C string library at my work now - I'll do an evaluation of libsrt.
As for ANSI C, maybe someday this will get folded into the standard and we can pass around ss_t* 's rather than char* 's whenever we use third-party libraries.
Thank you for the consideration. Although the library targets safe and cross-platform code, I don't recommend you using libsrt on production code, yet. Rationale: the API is not yet finished, and it could have some changes that could break your build. Suggestions are welcome :-)
P.S. I don't expect any standard committee adopting that, not even wide usage (I'm glad just having some feedback! :-D).
