qsort #include <cstdlib> void* qsort( const void *base, size_t num, size_t size, int (*compare)(const void *, const void *)); The function qsort() performs a Quick sort on an array. Note that some implementations may instead use a more efficient sorting algorithm. *base refers to the array being sorted. This array contains num elements, each of size size. The compare function accepts two pointers to the object within the array - which need to first be cast to the object type being examined. The function returns -1 if the first parameter should be before the second, 1 if the first parameter is after, or 0 if the object matches. Related topics bsearch
