NAME
qsort - sorts an array
SYNOPSIS
#include <stdlib.h>
void qsort(void *base, size_t nmemb, size_t size,
- int (*compar)(const void *, const void *))
DESCRIPTION
The qsort() function sorts an array with nmemb elements of
size size. The base argument points to the start of the
array.
The contents of the array are sorted in ascending order according to a
comparison function pointed to by compar, which is called with two
arguments that point to the objects being compared.
The comparison function must return an integer less than, equal to, or
greater than zero if the first argument is considered to be respectively
less than, equal to, or greater than the second. If two members compare
as equal, their order in the sorted array is undefined.
RETURN VALUE
The qsort() function returns no value.
