RE: node unique id

Hi Stefan,

Thank you very much for the response. The purpose is to the uniquely
identify a file for a specific revision or the latest revision.

What can I do if the file didn't change for a specified revision, then I
will need to get the latest revision number for the file, is there a API to
get the latest revision for a node?

Regards,

Ren

Yes, but it is specific to a particular filesystem instance.
If you dump/load the repository all IDs will change.

svn_fs_paths_changed2() declared in include/subversion/svn_fs.h provides the
IDs for changed paths in a particular revision.

An ID is represented as an opaque object svn_fs_id_t.
The contents of this object depend on the filesystem backend used.
There are a few functions to operate on svn_fs_id_t, such as
svn_fs_unparse_id().

It's unclear what purpose you'd like to use these for so it's hard to give
more specific advice.
