POSIX
The Portable Operating System Interface (POSIX) standardization
effort used to be run by the POSIX standards committee. During a
major overhaul of the names and numbers used to refer to this
project, PASC (Portable Applications Standards Committee) came into
being. So now the POSIX standards are written and maintained by PASC,
just so that you know.
The ability to check POSIX API calls (those that
have reached the status of
IEEE or ISO standards) comes as
standard with OSPC.
