You should define:
1) a pointer to info struct (struct info *
mymessage;)
2) a TOSMsg variable (TOS_Msg
tosmessage;)
and you should init (for example in
StdControl.init() ) like:
mymessage = (info *)
tosmessage.data;
then when you access you message field
you can do like
mymessage->name

Subject: [Tinyos-help] How to define a
struct using the payload of the TOSMsg
Hi,
A TOSMsg has 29 bytes of payload...For some convenience, I want to
convert these 29 in to a "struct", for examples
struct info {
char name[10];
uint8_t age ;
...
}
How do I go abt doing this so that in my program, I can just use things
like " John.name" or "John.age" (where
"John" is variable of the type "info") instead of using "msg.data[0]" or "msg.data[11]"....
Thanks for helping...
