8 The
<b>BOOST_PP_REPEAT_FROM_TO_D
</b> macro represents a fast horizontal repetition construct.
9 It reenters
<b>BOOST_PP_WHILE
</b> with maximum efficiency.
13 <b>BOOST_PP_REPEAT_FROM_TO_D
</b>(
<i>d
</i>,
<i>first
</i>,
<i>last
</i>,
<i>macro
</i>,
<i>data
</i>)
19 The next available
<b>BOOST_PP_WHILE
</b> iteration.
23 The lower bound of the repetition.
24 Valid values range from
<i>0</i> to
<b>BOOST_PP_LIMIT_MAG
</b>.
28 The upper bound of the repetition.
29 Valid values range from
<i>0</i> to
<b>BOOST_PP_LIMIT_MAG
</b>.
33 A ternary operation of the form
<i>macro
</i>(
<i>z
</i>,
<i>n
</i>,
<i>data
</i>).
34 This macro is expanded by
<b>BOOST_PP_REPEAT
</b> with the next available repetition depth,
35 the current repetition number, and the auxiliary
<i>data
</i> argument.
39 Auxiliary data passed to
<i>macro
</i>.
44 This macro expands to the sequence:
46 <i>macro
</i>(
<i>z
</i>,
<i>first
</i>,
<i>data
</i>)
<i>macro
</i>(
<i>z
</i>,
<i>first
</i> +
<i>1</i>,
<i>data
</i>) ...
<i>macro
</i>(
<i>z
</i>,
<i>last
</i> -
<i>1</i>,
<i>data
</i>)
50 The number of repetitions (i.e.
<i>last
</i> -
<i>first
</i>) must not exceed
<b>BOOST_PP_LIMIT_REPEAT
</b>.
53 The
<i>z
</i> value that is passed to
<i>macro
</i> represents the next available repetition dimension.
54 Other macros that have
<b>_Z
</b> suffix variants internally use
<b>BOOST_PP_REPEAT
</b>--for example,
<b>BOOST_PP_ENUM_PARAMS
</b> and
<b>BOOST_PP_ENUM_PARAMS_Z
</b>.
55 Using these
<b>_Z
</b> versions is not strictly necessary, but passing the
<i>z
</i> value (that is passed to
<i>macro
</i>) to these macros allows them to reenter
<b>BOOST_PP_REPEAT
</b> with maximum efficiency.
58 To directly use this
<i>z
</i> value, rather than simply passing it to another macro, see
<b>BOOST_PP_REPEAT_FROM_TO_D_
<i>z
</i></b>.
