27.12 C library algorithms [alg.c.library]

[Note 1:

The header <cstdlib> declares the functions described in this subclause.

— end note]

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);

Preconditions: For qsort, the objects in the array pointed to by base are of trivially copyable type.

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

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