Hi Charles,

indeed I am only interrested in the number of free chunks for a specific file system. (Maybe I was mistakable.) But the only
available information comes from "df" command or from /proc/yaffs.
Unfortunately we have 3 yaffs filesystems and I need the free chunks count from each single on, but /proc/yaffs has only one number
for me. :-(

Thanks, Stephan
