I suspect this is a non-controversial proposal with limited applicability and impact for most folks, and I hope to pass the RFC and implement the proposed code in trunk in a week or so.

Howard,

I would like to suggest the the CPLGetLastErrorUserData() be renamed something
like CPLGetErrorHandlerUserData().  It is *not* returning the user data
associated with the last error - but instead the user data associated with
the currently in-force error handler.   I'd also suggest that the functions
documentation include a note mentioning it is primarily intended for use from
within error handlers.

You also did not address if/how this will be exposed in SWIG languages.

Best regards,
