Thanks for clarifying superbonzo. If I understand it right, the map class is for parsing the description file. First I need to study the class more in depth.

But the C solution would be easier for...

Seems to me, I've described the whole problem wrong. :-/ Sorry for that.

On the bus you transmit and receive LIN messages in this simplified form:

ID (1byte), Data (2 - 4 - 8 bytes lenght...

You hit the nail S_M_A. We have a CANoe from VECTOR, but as you mentioned, its not really the cheapest one... and for some simpler tasks, where someone just needs to track the bus, its to complicated...

Hi Paul,

thank you very much for your reply. I'm not a C++ programmer. Can you be more specific regarding your example?
Lets say you receive on the bus the following message:

ID 10
Length 4...

Thanks for your reply, superbonzo, but your code snippet is not applicable. We have to separate the problem into two sections.
1) the application itsefl, which is able just to print out some text -...

Thanks for the reply, S_M_A.
Actually we have some sort of file with the frame descriptions, but imagine this:

You receive a message, according to the ID you identify the frame. So you have to go...

I receive messages over a bus. Suppose there is a function to read the messages storing them into a struct defined as follows:

typedef struct
