The BOOST_PP_TUPLE_INSERT_D macro inserts an element into a tuple.  It reenters BOOST_PP_WHILE with maximum efficiency.

Usage

BOOST_PP_TUPLE_INSERT_D(d, tuple, i, elem) (v)

Arguments

d
The next available BOOST_PP_WHILE iteration.
tuple
The tuple into which an element is to be inserted.
i
The zero-based position in tuple where an element is to be inserted.  Valid values range from 0 to BOOST_PP_TUPLE_SIZE(tuple).
elem
The element to insert.

Remarks

This macro inserts elem before the element at index i.
If the operation attempts to create an tuple that is larger than BOOST_PP_LIMIT_TUPLE, the result is undefined.
