qsort_r argument order


Apologies if this has come up before: it seems the mailing list archive search program can't handle search words with underscores in them.

I suppose this comment is coming too late, but I really wish that the qsort_r function had been done differently. As far as I can tell, qsort_r is not part of any standard, but it exists in BSD (including Mac OSX). For some reason that I can't comprehend, when it was added to glibc the argument order was permuted.


extern void qsort_r (void *__base, size_t __nmemb, size_t __size,
                     __compar_d_fn_t __compar, void *__arg)
  __nonnull ((1, 4));


void qsort_r(void *base, size_t nel, size_t width, void *thunk,
             int (*compar)(void *, const void *, const void *));

Why?! As far as I can tell, the functions would otherwise be compatible. Especially annoying is the fact that it still compiles -- it's only at runtime that it explodes in a fiery mess. As the developer of a software package that uses qsort_r and has to run on BSD and glibc, this is just a pain in the @$$.

Argh. Time to add a bunch of stupid preprocessor QSORT_Rs to my code.
