BOOST_PP_TUPLE_INSERT

The BOOST_PP_TUPLE_INSERT macro inserts an element into an tuple.

#### Usage

BOOST_PP_TUPLE_INSERT(tuple, i, elem) (v)

#### Arguments

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.
This macro uses BOOST_PP_WHILE interally. Therefore, to use the d parameter passed from other macros that use BOOST_PP_WHILE, see BOOST_PP_TUPLE_INSERT_D.

- BOOST_PP_TUPLE_INSERT_D

#### Requirements

Header: <boost/preprocessor/tuple/insert.hpp>

#### Sample Code

    #include <boost/preprocessor/tuple/insert.hpp>

    #define TUPLE (a, b, d)

    BOOST_PP_TUPLE_INSERT(TUPLE, 2, c) // expands to (a, b, c, d)
