[ns] Access Tcl Variable

[Jianxue Huang <jhuang@sce.carleton.ca>]

Hi, everybody:

Does any one know how to access Tcl variable from C++ ?

I tried to use
	Tcl_SetVar2(interp, "X", (char*) NULL, "value",0)
to assign "value" to a string variable named "X" in C++ program.  This is 
a Tcl libary function, and given in a book as a example.  But it does not 
work.  X is a variable defined in the Tcl script, right?

I want to change the value of a Tcl variable from C++.  Can anyone give me 
some help?

Thanks.
