title: Are the benefits of SFIO over STDIO still valid?
body: <p>I have just noticed about a library <a href="https://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.51.6574" rel="nofollow noreferrer">SFIO</a> for a safe and fast IO processing in C. But it is not very up to date. The last version of library is released in <strike>2005</strike> <a href="https://github.com/att/ast/tree/master/src/lib/libast" rel="nofollow noreferrer">2012</a> and I couldn't assess that if the claimed benefits of SFIO over STDIO are still valid with comparison to the recent releases of standard IO library. Also Would it be reasonable to use this library in a production code? </p>
