+ The BOOST_PP_LIST_TO_TUPLE macro converts a list to a tuple. +
+

Usage

+
+ BOOST_PP_LIST_TO_TUPLE(list) +
+

Arguments

+
+
list
+
+ The list to be converted. +
+
+

Remarks

+
+ If list is, for example, (a, (b, (c, BOOST_PP_NIL))), + this macro will produce: +
+ (a, b, c) +
+
+
+ Previously, this macro could not be used inside BOOST_PP_FOR.  + There is no longer any such restriction.  + It is more efficient, however, to use BOOST_PP_LIST_TO_TUPLE_R in such a situation. +
