The BOOST_PP_LIST_CAT macro concatenates all elements in a list.

Usage

BOOST_PP_LIST_CAT(list)

Arguments

list
The list whose elements are to be concatenated.

Remarks

Elements are concatenated left-to-right starting with index 0.
Previously, this macro could not be used inside BOOST_PP_WHILE.  There is no longer any such restriction.  It is more efficient, however, to use BOOST_PP_LIST_CAT_D in such a situation.
