Patch from Eric Norum <eric@cls.usask.ca> to implement this:
I'd like to propose a change to RTEMS task variables that I think would
make them more useful. I think that it is early enough in their
existence to still make changes to their API.
1) Change type from `int' to `void *'.
2) Add extra argument to task_variable_add -- if non-NULL, a pointer to
a `destructor' function to be called when the task exits. This function
would be called with that task's value of the task variable as its
argument. In many cases, the `dtor' function could be `free'.
rtems_status_code rtems_task_variable_add (
rtems_id tid, void **ptr, void (*dtor)(void *));
rtems_status_code rtems_task_variable_delete (rtems_id tid, void **ptr);
This would be all we'd need to cleanly and efficiently support C++
per-thread exception information without dragging in all that POSIX API
stuff.
