The BOOST_PP_TUPLE_TO_ARRAY macro converts a tuple to an array.

Usage

BOOST_PP_TUPLE_TO_ARRAY(tuple) (v)

or

BOOST_PP_TUPLE_TO_ARRAY(size,tuple) (v)

Arguments

size
The size of the tuple.  The argument is ignored.
tuple
The tuple to be converted.

Remarks

You can invoke the variadic macro (v) as BOOST_PP_TUPLE_TO_ARRAY(tuple) or BOOST_PP_TUPLE_TO_ARRAY(size,tuple) for backward compatibility.

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