You would either implement it copying from a suitably licensed (2-BSD)<br>
source, or do a clean-room implementation from the specification:<br>

I think it has to be a clean room implementation that is RTEMS specific. How else would you get thread execution time?</div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><br>
