zfs discuss - Aug 2008 - How to get a file''s crtime attribute from a znode?

I''m used to using fstat() and other calls to get
atime, ctime, and mtime values, but I understand that the znode also
stores a files creation time in crtime attribute.

Which system call can I use to retrieve this information?

You can use the getattrat() or fgetattr() interface to retrieve the 
create time attribute.  That interface returns an nvlist which has 
various supplemental attributes such as the create time.

You must have a ZFS version 3 file system for that interface to work.

If all you want is to see the create time then you can use "ls" to 
display it.

$ ls -% all <file>
