[ns] Bug in st.tcl/ns_mcast.tcl ?

[Andrea Josi <mr_josi@yahoo.it>]

Hi, 

in ~ns/tcl/mcast/st.tcl

we have:

ST instproc init {..} {
  ..............................
 set mctrl_ [new Agent/Mcast/Control $self]
 ..............................
}


and


ST instproc send-ctrl { which dst group } { 
   ....................................
   $mctrl_ send $which [$node_ id] -1 $group          
    ..............................
}


Neither in TCL nor in C++ i have found a "send"
instproc with 4 arguments, the following one, defined
in ~ns/tcl/mcast/ns_mcast.tcl,  has 5 arguments !

Agent/Mcast/Control instproc send {type from src group
args} 

What am i missing ?

Thanks a lot.

P.S. i still don't understand what are the tasks of
Agent/Mcast/Control that the ST agent can't take care
of thus making it necessary for Agent/Mcast/Control to
be used :(
