It's available (from memory) as a method in the C++ object. It is not
exported to TCL in stock code.

However, it is a *very* minor hack to source just prior to 'make' in order
to expose this interface. I found the very same problem when interfacing
a camera API to vtl and tcl via swig interface. It's a tiny hack, but works
entirely well.

So just a little source patching (very intuitive for this minor bit) is 
all that
is required. Hopefully these are inspiring words.....
