Library Functions
QSORT
Synopsis
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 pointers to two items to be com-
pared. 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.
Example
#include <stdlib.h>
void qsort (void * base, size_t nel, size_t width,
int (*func)(const void *, const void *))
#include <stdio.h>
#include <stdlib.h>
int aray[] = {
};
int
sortem (const void * p1, const void * p2)
{
}
void
main (void)
{
567, 23, 456, 1024, 17, 567, 66
return *(int *)p1 - *(int *)p2;
register int i;
