Hello,
Would you like to know how many named function parameters are used in the source files?
How do you think about to try the following semantic query approach out a bit more?

I am not sure that i understand these result.
Does that mean there are actually functions taking 22 arguments ?

I think the results are dubious. Only 29 functions with no parameters? That can't be right.

Functions with no parameters should have a parameter list of the form
(void). So 29 would be a high number...

(with the help of the software "Coccinelle 1.0.0-rc23") interesting
for further considerations?
