This looks nicely done overall, and I appreciate the perf test. The speed looks like a reasonable outcome. I'm torn on the qsort_r() demo patch. I don't think it looks too bad. OTOH, I don't think I would want to deal with the opposite-argument-order versions. Is there any interest in people adding the ISO qsort_s() to their libc implementations? It seems like it's been a fair number of years by now. -Peff
