fbextPP_TupleElem

# define fbextPP_TupleElem(size,
index,
tuple) fbextPP_TupleElem__##size##__##index tuple

gets the element value at position index stored in the tuple tuple of size size.

For example, if size is `3`, index is `1`, and tuple is `(a,b,c)`, then this macro expands to `b`.

Parameters

sizeis the count of elements in the tuple.
indexis the position of the element value to retrieve.
tupleis the tuple which stores the element to retrieve.
# define fbextPP_TupleElem(size,
