Hi,
I have a variable in Trace class (trace.h). That named ntcCount_
I want to access this variable using tcl:
I use bind("ntcCount_", &ntcCount_);
and in tcl file:
set mytrace [new Trace]
and get value of this variable:
puts "value = [$mytrace set ntcCount_]"
But I Can't. Some error occur.
Please help me.
thanks
