Accessing C union structures with MCL

[tom@opus.nmsu.edu (Thomas C. Eskridge)]

I have a C program that uses a Union structure as a principal data type that I
would like to access from MCL.  So, the Union, called a Var, has a type (one of
function, integer, float, structure, etc) and then the actual data.  I've
looked briefly at the brief documentation in the manual, with little success in
solving this problem.  Does anyone have some example code they would be willing
to share?
