The BOOST_PP_ARRAY_ENUM macro converts an array to its comma-separated elements. The comma-separated elements are in the form of variadic data.

Usage

BOOST_PP_ARRAY_ENUM(array)

Arguments

array
The array whose elements are to be converted.

Remarks

This macro expands to a comma-separated list of the elements in array.  For example, BOOST_PP_ARRAY_ENUM((3,(x,y,z))) expands to...
x, y, z

    In C++ 20 mode if the array is empty the resulting variadic data will be empty.

Requirements

Header:  <boost/preprocessor/array/enum.hpp>

Sample Code

#include <boost/preprocessor/array/enum.hpp>

#define ARRAY (5,(B,O,O,S,T))

BOOST_PP_ARRAY_ENUM(ARRAY) // expands to B, O, O, S, T
