So I've got it down to this:

%typemap(in,fragment=3DSWIG_AsVal_frag(size_t))(int maxLen,char * =
outStr)
(int res,size_t size, Char * buff=3D0)
{
        // FAFAFAf
        res =3D SWIG_AsVal(size_t)($input,&size);
        if(!SWIG_IsOk(res))
        {
                %argument_fail(res,"(SIZE,TYPEMAP)",$symname,$argnum);
        }
        buff=3D%new_array(size+1,Char);
        $1 =3D %numeric_cast(size,$1_ltype);
        $2 =3D %static_cast(buff,$2_ltype);
}
%typemap(freearg,noblock=3D1,match=3D"in")(int maxLen,char * outStr)
{
        if(buff$argnum)
        {
                %delete_array(buff$argnum);
        }
}
%typemap(argout,noblock=3D1,fragment=3D#SWIG_FromCharPtr)(int =
maxLen,char *
outStr)
{
        %append_output(SWIG_FromCharPtr($2));
}

However, I'm getting syntax errors from swig on the line with
#SWIG_FromCharPtr... If I remove the fragment=3D... Then its happy... I
don't know whats going on, as I have just copied these typemaps from
cstrings.swg.

Any ideas/suggestions?

Thanks!
