<h2><a name="BOOST_PP_REPEAT">#define BOOST_PP_REPEAT</a>(COUNT,MACRO,DATA)</h2>
|
|
<p>Repeats the macro <code>MACRO(INDEX,DATA)</code> for <code>INDEX = [0,COUNT)</code>.</p>
|
|
|
|
<p>In other words, expands to the sequence:</p>
|
|
|
|
<pre>
|
|
MACRO(0,DATA) MACRO(1,DATA) ... MACRO(<a href="dec.htm#BOOST_PP_DEC">BOOST_PP_DEC</a>(COUNT),DATA)
|
|
</pre>
|
|
|
|
<p>For example,</p>
|
|
|
|
<pre>
|
|
#define TEST(INDEX,DATA) DATA(INDEX);
|
|
<a href="repeat.htm#BOOST_PP_REPEAT">BOOST_PP_REPEAT</a>(3,TEST,X)
|
|
</pre>
|
|
|
|
<p>expands to:</p>
|
|
|
|
<pre>
|
|
X(0); X(1); X(2);
|
|
</pre>
