[Swig-user] Can an argout typemap be made only apply to functions with no return (void)?

[James M. <jam...@gm...>]

Hi,

I have been scrambling for the past few weeks to pickup using SWIG and I've
been able to deal with a number of issues by consulting the documentation,
web pages, forum postings, etc.  However, I can't seem to find an answer to
a problem that I'm currently facing.  I would like to create an argout
typemap for functions matching a certain set of input parameters.  The
library that I'm converting is very large (nearly 2k C++ classes) and I
would like to ensure that the argout typemap only applies to functions that
don't return anything already (void return).  If the function already has a
return value, then I don't want the argout typemap to apply.  Is this
possible?  Here is a simplified example:

%typemap(argout) (const int &a, double &b) {
  //FINDME
}

class Foobar {
public:
  Foobar();
  void test(const int &a, double &b);  // Apply to this function (void
return)
  int test2(const int &a, double &b);  // Do NOT apply to this function (int
return)
  ~Foobar();
};

Thanks,
-James
