Using a command function to access a C++ from ns

[Christopher May]

Hi,

I wrote previously about an error that I get when I try to access a C++ 
function from NS using a Agent::command function. I have made slight 
progress, but know have arrived at another error. When I use the following 
line in a script

$ns at $swtm "$node(nd) cmd send_sols"

I get the following error, does anyone know what this means. thanks in 
advance

ns: _o28 cmd send_sols:
    (_o28 cmd line 1)
    invoked from within
"_o28 cmd send_sols"

Chris
