I tried this approach, but it seems that JS_SetOpaque() / JS_GetOpaque() can
be used only for clases, QuickJS crashes of I use JS_SetOpaque() to a
function object created by JS_NewCFunction(). And JS_GetOpaque() needs anyway
a class ID...

You can use JS_SetOpaque to attach a void* to a JSValue object. Maybe
this is what you are after?

Hello,
JSValue can carry reliable a pointer? At this moment it seems that the
only method is to cast the pointer to an int64, but it looks a bit hacky
to me.
Example:
===========================
Convert the pointer to int64:
[...]
JSValue ptr[1] = { JS_NewInt64(ctx, reinterpret_cast<int64_t>(this)) };
JS_SetPropertyStr(ctx, global_obj, "print", JS_NewCFunctionData(ctx,
js_print, 1, 0, 1, ptr));
[...]
Convert back to pointer:
static JSValue js_print(JSContext *ctx, JSValue this_val, int argc,
JSValue *argv, int magic, JSValue *func_data)
{
ICEJsEngine *jse;
JS_ToIndex(ctx, (uint64_t*)&jse, *func_data);
[...]
}
===========================
Or maybe my approach is not right?
Thanks.
