This is an oddity. I don't usually ask questions around here.
My issue is this, using macros you can do the following...
#define DOIT(typename) const char *typename ## _STR = #typename ;
DOIT(ClassName)
where DOIT(ClassName) will expand to the following...
const char *ClassName_STR = "ClassName";
My question is, can you do the equivalent with templates? Or some other way without using macros.
another possible approach is typeid

thanks. that's a very good answer for the question that I asked. I'm afraid I asked the wrong question though.
What I have now, that I wish to replace is a macro that in addition to what I said above, does this:
DECLARE_A_STRUCT (structname,
int blah1;
int blah2;
float blah3;
)
and it expands to:
struct structname
{
int blah1;
int blah2;
float blah3;
};
const char *structname_str = "int blah1; int blah2; float blah3;";
The basic idea here is to provide a string version of the declared struct. I hate it of course. Any ideas?
The only way to do what you want involves macros. Or explicitly providing the string yourself eery time which, I presume, is what you wish to avoid.
that's what I thought. It's a sad attempt by me to mimic some of the "reflection" features of other languages.
CORBA libraries (or ORBS) and, IIRC, other systems like DCOM support reflection capabilities. They way they achieve that in in C or C++ involves code generation (eg mapping an interface specification to C++) or hard-coded types with defined library support. That is probably overkill for what you want -- it's intended to support a generic interface to distributed objects.
