15 | !!DESCRIPTION | ||
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 | ||
35 | |||
36 | |||
37 | The __qsort()__ function returns no value. | ||
