QSORT
Synopsis
#include <stdlib.h>
void qsort (void * base, size_t nel, size_t width,
int (*func)(const void *, const void *))
Description
The qsort() function is an implementation of the quicksort algorithm. It sorts an array
of
nel items, each of length width bytes, located contiguously in memory at base. The
argument
func is a pointer to a function used by qsort() to compare items. It calls
func with s to two items to be compared. If the first item is considered to be greater
than, equal to or less than the second then
func should return a value greater than
zero, equal to zero or less than zero respectively.
