!!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.
