qsort(3F)

NAME
     qsort - quick sort

SYNOPSIS
     subroutine qsort (array, len, isize, compar)
     external compar
     integer*2 compar

IMPLEMENTATION
     IRIX systems

DESCRIPTION
     One dimensional array contains the elements to be sorted.  len is the
     number of elements in the array.  isize is the size of an element. The
     following sizes are normally used:

     4         for integer and real

     8         for double precision or complex

     16        for double complex

     (length of character object)
               for character arrays

     compar is the name of a user supplied integer*2 function that
     determines the sorting order.  This function is called with 2
     arguments that are elements of array. The function returns the
     following:

     negative
          if arg1 is considered to precede arg2

     zero if arg1 is equivalent to arg2

     positive
          if arg1 is considered to follow arg2

     On return, the elements of array are sorted.
