File name wild cards

[Bill Findlay <findlaybill@blueyonder.co.uk>]

Can anyone point me to a portable way of doing wildcard filename lookups?

In Ada.Directories we have;

> type Search_Type is limited private;
> procedure Start_Search (Search: in out Search_Type;
> Directory: in String;
> Pattern: in String;
> Filter: in Filter_Type := (others =>  True));

etc
But the interpretation of Pattern is implementation defined.
Worse, I cannot find any interpretation in the GNAT documentation.
