16
17
18 The __qsort()__ function sorts an array with ''nmemb''
19 elements of size ''size''. The ''base'' argument
20 points to the start of the array.
21
22
23 The contents of the array are sorted in ascending order
24 according to a comparison function pointed to by
25 ''compar'', which is called with two arguments that point
26 to the objects being compared.
27
28
29 The comparison function must return an integer less than,
30 equal to, or greater than zero if the first argument is
31 considered to be respectively less than, equal to, or
32 greater than the second. If two members compare as equal,
33 their order in the sorted array is undefined.
34 !!RETURN VALUE
