[Michal Nowikowski]

Hello

I'm writing a frontend for some small language. I've got few problems.
First: how to build a function with 'char *' parameter - in examples (toy,
spl, flim, treelang languages) I have analysed there are only simple
function with integers as arguments.
Second: how to build a call to function from library e.g. printf. I'd like
to add to generated code some calls to functions defined in some library.
Example in my language, there is instruction:
 print "blah";
so how to call print function from stdio.h.

Best regards
Godfryd

Michal,

Take a look at the Objective-C front-end, specifically 
gcc/objc/objc-act.c.
In it you'll see prototypes for many functions being defined 
(objc_msgSend, etc.)
and then the functions getting called (via build_function_call()).

Pozdrowienia,
