| Can anyone explain in detail what is the use of the functions like
TCL_evalFile. I understand that this evaluates the content of the file
as tcl script. But I do not exactly understand what kind of file is
converted to what and where does it return the changed file etc.
It will be great if anyone could suggest an online tutorial/book for
the same.
Thanks,
Puneet

Basically you provide it a name of a file to evaluate a good example
is : http://wiki.tcl.tk/17047
where the Swig is used to produce a dynamic module to allow the script
to modify a C structure using EvalFile

There is no "converting" or changing of the file, it just evaluates it.
the file in question should be a valid Tcl script.

But how exactly does it evaluate? Do you know any nice tutorial for
that?

I'm not sure I understand - it evaluates it by the basic rules of the Tcl language.
the script equivalent would be
source filename
it runs the file throught he Tcl interpreter and that evaluates the commands in the script.
