Re: [Boost-users] How to set a search mask with wild card for directory_iterator ?

Silvio,

you have to implement it yourself. You could use a boost regular expression
lib or xpressive lib, to match mask(s) with file names found. I would
suggest to take a look at boost iterator lib. Using the regex to match the
mask + wrapping the directory_iterator into filetered_iterator will do the
job.

Best Regards,
Ovanes
