The paper talks about a very small portion of POSIX. I thought they'd mention things like http://pubs.opengroup.org/onlinepubs/009695399/functions/hsearch.html

The paper talks about a very small portion of POSIX. I thought they'd mention things like http://pubs.opengroup.org/onlinepubs/009695399/functions/hsearch.html http://pubs.opengroup.org/onlinepubs/009695399/functions/hse... . For the record, I'm always sad when I can't do everything I want in POSIX and need to use, say, Apache APR (to support Windows), or the C++ standard library (to support Windows), especially in cases where I don't stray far from what POSIX supports. (I am not sad when I use something that actually adds value over POSIX; e.g., I like using C++ regexes instead of POSIX regexes because I don't have to guess how many matches I might have; and I'm happy to use std::unordered_map -- or the APR equivalent -- because I can have more than one at a time).
