Re: [ns] too many arguments

[John Mehringer <mehringe@ISI.EDU>]

Any arguments passed that have spaces maybe mistaken as 2 arguments.  It
is best to put {} around your tcl arguments so that tcl will know for
sure to treat a string with a space as one argument.

Try using this:
tcl.evalf("[{%s} set node_] leave-group {%s} {%d}",agent_->name(),
agent_->name(),groupaddr);

and see if it fixes the problem.
