Yes, does not make much of a difference though.

How does extern "C" and namespaces mix?
Remember that this has to be a 'C'-api.

sorry, but I do not understand this sentence completely.
but! I am not introducing more pimpls, more like the first step is
going towards a dynamically loaded frontend gui.
Imagine:
(pseudo code)
class Dialogs {
void showSomeDialog() {
staitc function0<void) sSd = getGUISymbol<void>("showSomeDialog");
if (!sSd.empty()) {
sSd();
} else {
// error finding symbol
}
}
};
template<Type>
function<Type> getGUISymbol(string & funcBaseName) {
string symbolname = frontendgui + funcBaseName;
return dl_sym(symbolname.c_str());
}
xforms: liblyxxforms.so
guiapi.C
void xformsshowSomeDialog();
qt: liblyxqt.so
guiapi.C
void qtshowSomeDialog();
This is taking several shortcuts... but you should get the idea.
Of course if you have a better solution I want to learn it.
