My feeling is POSIX is still pretty important in the safety critical embedded world. Green Hills Integrity, VxWorks, QNX, RTEMS all have some market presence and aim for POSIX compliance.
- skissane 6y agoOut of those, it appears that only Green Hills Integrity and VxWorks have any formal POSIX certification – http://get.posixcertified.ieee.org/register.html http://get.posixcertified.ieee.org/register.html – and only the first is actually certified against the full 1003.1 standard, VxWorks is only certified for the PSE52 realtime subset To "aim for POSIX compliance" without formal certification doesn't mean much, since to "aim for POSIX compliance" is compatible with supporting an arbitrary subset of the POSIX standard
