SYNOPSIS

mixed *sort_array(mixed *arr, string greater_fun, object|string ob)
mixed *sort_array(mixed *arr, closure cl)

DESCRIPTION

Returns an array sorted by the ordering function ob->greater_fun(a, b), resp by the closure expression. If 0 is given as first argument, 0 is returned.

The function 'greater_fun' in the object 'ob' (which may be also given as its file_name) is continously passed two arguments which are two of the elements of the array 'arr'. It should return true or a positive number if the first argument is greater than the second.
