Why should I care at all about POSIX when not using C or porting UNIX software?<p>POSIX is just the part of UNIX that should have been part of the C runtime, but instead they made it into an optional standard.<p>Almost ever other programming language with richer runtimes don&#x27;t have any need to depend on POSIX.<p>All their APIs for creating processes, threads, accessing file systems, communicating over the network aren&#x27;t POSIX dependent.
