<h3><a name="BOOST_PP_ENUM_PARAMS_WITH_A_DEFAULT">#define BOOST_PP_ENUM_PARAMS_WITH_A_DEFAULT</a>(COUNT,PARAM,DEFAULT)</h3>
|
|
<p>Generates a comma separated list of parameters with a default.</p>
|
|
|
|
<p>In other words, expands to the sequence:</p>
|
|
|
|
<pre>
|
|
<a href="cat.htm#BOOST_PP_CAT">BOOST_PP_CAT</a>(PARAM,0) = DEFAULT,
|
|
<a href="cat.htm#BOOST_PP_CAT">BOOST_PP_CAT</a>(PARAM,1) = DEFAULT,
|
|
...,
|
|
<a href="cat.htm#BOOST_PP_CAT">BOOST_PP_CAT</a>(PARAM,<a href="dec.htm#BOOST_PP_DEC">BOOST_PP_DEC</a>(COUNT)) = DEFAULT
|
|
</pre>
|
|
|
|
<p>For example,</p>
|
|
|
|
<pre>
|
|
<a href="enum_params_with_a_default.htm#BOOST_PP_ENUM_PARAMS_WITH_A_DEFAULT">BOOST_PP_ENUM_PARAMS_WITH_A_DEFAULT</a>(3,x,y)
|
|
</pre>
|
|
|
|
<p>expands to:</p>
|
|
|
|
<pre>
|
|
x0 = y, x1 = y, x2 = y
|
|
</pre>
