[ns] How to get the Nodes' coordinate from TCL to C++

[Mathiew Moussa]

Hello Walid,

Thanks for the reply.

You said getting the coordinates from the TCL file easier... i have  
them stored in a topography.tcl file (or so i recall) that has the X Y  
Z coordinates of each sensor.

So what's the way to get them from the TCL file directly to be used in C++ ??

Thanks alot,
Mathiew
