Close.  In general, you convert the POSIX-style path to an FSRef (in 
Carbon this would be FSPathMakeRef; in Python you can also use 
Carbon.File.FSRef()).  Then, call FSGetCatalogInfo and get the FSSpec.  
Look inside the FSSpec for the name.  That's the name used by 
traditional Mac OS 9 style paths.  (Note that there is no such thing as 
a Unicode path as far as the Carbon File Manager is concerned).

Here's what you'd use to get just the name:
print Carbon.File.FSRef('/').FSGetCatalogInfo(0)[2].as_tuple()[2]

The first [2] gets the FSSpec output from FSGetCatalogInfo.  The second 
[2] gets the name out of the FSSpec.
