Hi all, we ran into some issue where we have to wait on the termination of a native real-time userspace thread during cleanup. This can be done in a custom way of course, either via some polling on a flag or by blocking on a standard posix semaphore that are signalled by the terminating real-time thread. But maybe it is more useful to have a generic function available with the native skin.
The problem is now that the pthreads underneath the real-time threads are created with PTHREAD_CREATE_DETACHED. Changing this also changes the semantic of other rt_task_xxx functions as posix then requires the creator to call pthread_join (i.e. a new rt_task_join) in any case. A better option might be to introduce a new mode bit T_JOINABLE to decide if the related pthread should be created detached or not. Default would remain PTHREAD_CREATE_DETACHED, if rt_task_join is to be used, T_JOINABLE could be passed to rt_task_create. What do you think, worth the effort? Jan
