[Tinyos-help] Question on MultiOscilloscope Application

[M A]

Hi

I have started learning tinyos-2.x and I have a simple question related to
MultiOscilloscope function in directory tinyos-2.x/apps/MultihopOscilloscope.
In the file MultioscilloscopeC.nc we declare a message buffer " message_t
uartbuf ". But I dont understand where is this initialized. We call the
command SerialSend.getPayload(&uartbuf); in the Recevie.receive() event.
Thus  basically we are getting the payload from the message stored in
uartbuf. But I cant figure out where and when a message is being stored in
uartbuf.

I guess when Receive.receive returns it returns a buffer for the stack. Is
it the same buffer? I am confused. Can anyone explain this to me ?

Thanking You
John
