This is very easy to do, see my previous posts. Otherwise, get a book on Tcl (eg
Ousterhoust's) and read up on the Tcl C interface. It's a very painless
procedure to invoke Tcl scripst from within C, and to register C functions with
Tcl.

An example of code that does this is at:

http://www.cse.psu.edu/~vance/scald-src-0.90.tar.gz

See files scald.cpp and useri.cpp for initializing Tcl and registering callback
functions. Notice the little trick I had to do to register class methods as
callback functions, by using a static router function.
