                     18: .I Qsort
                     19: is an implementation of the quicker-sort algorithm.
                     20: The first argument is a pointer to the base of the data;
                     21: the second is the number of elements;
                     22: the third is the width of an element in bytes;
                     23: the last is the name of the comparison routine
                     24: to be called with two arguments which are pointers
                     25: to the elements being compared.
                     26: The routine must return an integer less than, equal to, or greater than 0
                     27: according as the first argument is to be considered
                     28: less than, equal to, or greater than the second.
