[PD] pathname of parent patch?

[Julian Peterson]

Hello all--

Is there a way to get the directory of the parent patch?  I have an  
object (csoundapi) which does it's own path handling and does not  
automatically search the directory of the parent patch.  This  
severely limits the portability of a patch.  Is there an object or  
method of getting the directory of the parent patch for use with  
makefilename?

The only post I've found on this issue is this one:
