difference between st_atime, st_mtime and st_ctime

Hi there,

I m just wondering if someone could explain me the difference between these three timestamps. All I know is that

st_atime: time of last access
st_mtime: time of last data modification
st_ctime: time of last file status change

Well, for me, last access time is clear that should be the time the file is opened the last time, right? But the last two ones? What happens if I copy or rename a file, what changes? Or what happens when I resize a picture?

Thanks

mtime is when you open the file for "w" or "a"
ctime is when you do chmod(), and a few other things which I can't remember without RTFM

See this.
My understanding was ctime dealt with changes to the inode, but according to the URL I posted it also gets updated with file content changes.

EDIT: Experimented...
ctime does change when file contents change. Make a test file, change its name, contents etc, and watch how the times change. You can view them easily with the "stat" command. (ie, "stat testfile.txt")
