[Swig-user] automating C++ callback bindings for use in Python/Go

[Brad B. <bba...@at...>]

Hi,
     I am a new SWIG user and have a question about its use when dealing 
with callbacks
from a C++ library.  I have generated the bindings for the library APIs 
successfully.  However
there is one functionality that uses a callback function for async event 
handling.  I want
to use SWIG to create the APIs for Python and perhaps Go.  So there are 
a couple of issues
here, perhaps more that I don't know about yet:
1-  Is there any support in SWIG that could help with this, or is 
callback handling a roll
      your own solution kind of thing
2-  what is the general approach to this, if I want to support multiple 
languages from the
     library?  How can the library support multiple languages above it  
in such a
     way as to avoid re-writing that part of the library for every new 
language binding?
Thank you.
