Hello e people,I have written a little example app for eio_file_stat_ls() that could have its place under "trunk/eio/src/examples/" or "trunk/EXAMPLES/eio/".
I think this could help people that needs to use it.It also warns about the filter_cb being called in eio's thread. A trap i stepped on by badly reading the doc (totally my fault).
Example file is attached to this mail.
/*
* Compile :
* gcc -g -o eio_file_stat_ls eio_file_stat_ls.c `pkg-config --cflags --libs eina ecore eio`

* Prepare :

* touch test/excluded
* touch test/backuped
