The BOOST_PP_TUPLE_TO_ARRAY macro converts a tuple to an array.

Usage

BOOST_PP_TUPLE_TO_ARRAY(size,tuple)

or

BOOST_PP_TUPLE_TO_ARRAY(...) (v)

Arguments

size
The size of the tuple.  Valid tuple sizes range from 1 to BOOST_PP_LIMIT_TUPLE.
tuple
The tuple to be converted.

Remarks

The size argument must be the actual size of the tuple.

You can invoke the variadic version (v) as BOOST_PP_TUPLE_TO_ARRAY(tuple) or BOOST_PP_TUPLE_TO_ARRAY(size,tuple).

Requirements

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

Sample Code 

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

#define TUPLE (a,b,c)

BOOST_PP_TUPLE_TO_ARRAY(3,TUPLE) // expands to (3, (a, b, c))

// or for the variadic version (v)

BOOST_PP_TUPLE_TO_ARRAY(TUPLE) // expands to (3, (a, b, c))
