"TOS_MsgPtr Msg" is a pointer and you must initialize it to an allocated
location. For example,
TOS_Msg buf
TOS_MsgPtr msg = &buf
and then copy "Hello" to msg->data using either memcpy or any
other string copy routines. If you look at TOS_Msg structure defined in
tos/system/AM.h has a "length" field.
However, if you are just starting to use Tinyos, I sugest you to start
with Tinyos-2.x.
