That's a good idea, but I wouldn't introduce such class without some 
usages at least.

I'd recommend considering immediately upgrading the proposed functions 
to use SortDirection and redefine the constants in terms of the enum.

I.e. set const SORT_ASC = SortDirection::Ascending; - similar for others 
like the SCANDIR_SORT_DESCENDING etc..

This is a reasonable BC break, which is also trivially fixed by simply 
accepting int|SortDirection in existing functions.


Thanks,
Bob
