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.
