Hi Bibudh,
Thanks a lot for your quick response.
The python script that I use for simulation adds channel "Log" to stdout.
Some of the dbg statements that I have in my program do get printed. Do I
still need to use the dbg mode as you described?
I am pasting my simulation script below.
Thanks,
--Mehedi
import sys
from TOSSIM import *
t = Tossim([])
t.addChannel("Log",sys.stdout);
t.getNode(1).bootAtTime(1000)
t.getNode(2).bootAtTime(1002)
for i in range(0,400000):
t.runNextEvent()

U need a debug mode, e.g.,
dbg(DBG_TEMP, "Counter: Value is %i\n", (int)state);
here the mode is 'temp'. To get the message in the console, u need to
export the debug mode with the following command before u run the program.
export DBG=temp
