This is wrong. We're passing parent data and also setting the parent
name with a string the original way. Do you have a parent?

There are a handful of these wrappers now. Can we have one function that
takes all possibilities and then static inline functions that call one
exported function?  We can pass some structs to that function to keep
the argument count "low", so those structs live on the stack for a short
time.
