What I am doing is basically looking for a function with a name like:

def on_canmsg( id, dlc, data, time ):
	## catch all for CAN messages
	## do something

def on_canmsg_100( id, dlc, data, time):
	## message id 100 handler
	## do something different

Based on the function name I know that the first is a catch all for CAN
messages and the second is for handling a message with an identifier of 100.
The big BUT that I have is what if they define the functions like below:

def on_canmsg( a, b ):
	## catch all for CAN messages
	## incorrect arguments

Then when the function is called from the C-API it would not do as it
should. So what I want to do is to inspect the list of argument names, I
know I can't check what types the function composer uses/assumes but if I
can atleast check the names they use then I will have atleast some
confidence in the function being correct. I need to do this from the C-API
and would rather avoid having to call a script to check a script.

So any suggestions?

TIA
