[Swig-user] Convert C return value to exception, typemap away retval

[Eliot <el...@bl...>]

Hi,

I have a C library where all functions are of the form

error_code Func(inparam, * outparam)

I want to convert the error_code to a python exeception, this works fine:

%exception {
	$action
	if (result) {
		PyErr_Format(PyExc_Exception,"ASX error %d",result);
		return NULL;
	}
}

BUT the wrapper function still returns the zero error code.

Func(inparam) => (0,outparm)

Is there a way to get rid of/ignore the return value?

thanks

Eliot
