I'm not sure what you're trying to say. The Portable Operating System Interface (POSIX) is specified in an ISO standard, and basically specifies what a UNIX operating system's programmable interfaces are.

POSIX also specifies stuff like "awk must be made available". Is that what you think the C programming language specifies?
