Name
       qsort - quicker sort

Syntax
       #include <stdlib.h>

       void qsort(base, nel, width, compar)
       void *base;
       size_t nel, width;
       int (*compar)();

Description
       The subroutine is an implementation of the quicker-sort algorithm.  The
       first argument is a pointer to the base of the data; the second is  the
       number  of elements; the third is the width of an element in bytes; the
       last is the name of the comparison routine to be called with two	 argu‐
       ments  which  are pointers to the elements being compared.  The routine
       must return an integer less than, equal to, or greater than 0 according
       as  the	first  argument	 is  to	 be considered less than, equal to, or
       greater than the second.
