Maybe I'm missing something, but... src/newlib/libc/include/stdlib.h: _VOID _EXFUN(qsort,(_PTR __base, size_t __nmemb, size_t __size, int(*_compar)(const _PTR, const _PTR))); _PTR _EXFUN(bsearch,(const _PTR __key, src/newlib/libc/search/qsort.c src/newlib/libc/search/bsearch.c They look there to me.
