The BOOST_PP_LIST_TO_ARRAY macro converts a list to an array.

Usage

BOOST_PP_LIST_TO_ARRAY(list)

Arguments

list
The list to be converted.

Remarks

This macro uses BOOST_PP_WHILE. Within BOOST_PP_WHILE, it is more efficient to use BOOST_PP_LIST_TO_ARRAY_D.

If the list to be converted is empty, as represented by 'BOOST_PP_NIL', the resulting array is empty, as represented by '( 0, () )'.
