Hi,
Both RTLinux (beta16) and RTAI (version 0.6) are very stable, and both
have support for pthreads.
The main differences in the pthreads support that I'm aware of are:
- RTAI has support for conditional variables and priority inheritance
mutexes whereas RTLinux does not.
- RTAI has support for dynamic thread creation, whereas in RTLinux all
the threads must be created at init_module time.
Hope this helps,
Best regards,
Steve Papacharalambous
