In this implementation 23of the library, ``BOOST_MPL_LIMIT_UNROLLING`` has a default value of 4. To 24override the default, define ``BOOST_MPL_LIMIT_UNROLLING`` to the desired 25value before including any library header. 26|preprocessed headers disclaimer| 27 28 29Example 30------- 31 32Except for overall library performace, overriding the 33``BOOST_MPL_LIMIT_UNROLLING``\ 's default value has no user-observable effects. 34 35See also 36-------- 37 38|Configuration|, |BOOST_MPL_CFG_NO_PREPROCESSED_HEADERS| 39 40 41.. copyright:: Copyright � 2001-2009 Aleksey Gurtovoy and David Abrahams 42 Distributed under the Boost Software License, Version 1.0.
