Directory masks -- howto?

Hi Denis,

My KDE gui frontend is almost ready for initial release. Masks are giving 
me a problem though. This is the "-P" option to dar which I am trying to 
implement in the gui.

Here is the synopsis:
Suppose I want to exclude a directory which contains the backup archive 

exdir="/home/john/kdar/backups";

from an archive whose root is 

rootdir="/home/john/kdar/";

I construct the subtree mask:

et_mask subtree;

Then I construct an exclusion mask:

ou_mask exclus;

Then with the add_mask() method, 

exclus.add_mask(simple_mask(exdir));

And then add exclus to the subtree:

subtree.add_mask(not_mask(exclus));

libdar then warns (from op_create) that the backup archive 
is in one of the directories that will be backed up, and an infinite loop 
might result!
It works fine when I have two "-P" type arguments:
exdir1="/home/john/kdar/backups"
exdir2="/home/john/kdar/backups/*"
exclus.add_mask(simple_mask(exdir1));
exclus.add_mask(simple_mask(exdir2));

The command line version of libdar does not require me to have both "-P" 
arguments for the backup to be excluded, I just need "-P backups". How do 
I make it as simple using libdar directly?

Thanks,
JB

P.S. some screenshots of KDar can be found at

Any suggestions?
