void* bsearch(const void* key, const void* base, size_t nmemb, size_t size,
              c-compare-pred* compar);
void* bsearch(const void* key, const void* base, size_t nmemb, size_t size,
              compare-pred* compar);
void qsort(void* base, size_t nmemb, size_t size, c-compare-pred* compar);
void qsort(void* base, size_t nmemb, size_t size, compare-pred* compar);

Effects: These functions have the semantics specified in the C standard library.

Preconditions: The objects in the array pointed to by base are of trivial type.

Throws: Any exception thrown by compar ([res.on.exception.handling]).
