Hello rtlinux, regarding the seemingly patchy implementation of POSIX routines on Linux or rtlinux.........basic stuff such as shared memory (apart from mmap) and semaphore routines seem to be absent - no defs in unistd.h. Am I missing something, do you know of any move to implement this stuff or am I condemned to use Sys V for the foreseeable Linux future?....I'm trying to wean our real-time VME-based systems off LynxOS.
