How to set a variable in script for a c++ file variable

[nagaraju516]

Hello frnds, I joined today in this group.
I am working in Expect. I am writing one script which I want to set a variable value in c++ file. But I am getting error "Namespace doesn't found".

Please anyone can help me in this regard.

Regards,
Nagaraju

Hi,

a little more information would likely help solve your problem.

But I guess you want to link a TCL variable to a variable in your c++ program. So whenever you change the TCL var (using set, ...) the c++ var will be updated accordingly. All you have to do is call Tcl_LinkVar(interp, varName, addr, type) in your c++ code.
Parameter type: Must be one of TCL_LINK_INT, TCL_LINK_DOUBLE, TCL_LINK_WIDE_INT, TCL_LINK_BOOLEAN, or TCL_LINK_STRING, optionally OR'ed with TCL_LINK_READ_ONLY to make Tcl variable read-only.
