<div style="margin-left: 0px;">
The <b>BOOST_PP_SEQ_TRANSFORM_S</b> macro transforms each element in a <i>seq</i>
according to a supplied transformation. It reenters <b>BOOST_PP_SEQ_FOLD_LEFT</b>
with maximum efficiency.
</div>
<h4>
Usage
</h4>
<div class="code">
<b>BOOST_PP_SEQ_TRANSFORM_S</b>(<i>s</i>, <i>op</i>, <i>data</i>, <i>seq</i>)
</div>
<h4>
Arguments
</h4>
<dl>
<dt>s</dt>
<dd>
The next available <b>BOOST_PP_SEQ_FOLD_LEFT</b> fold step.
</dd>
<dt>op</dt>
<dd>
A ternary predicate of the form <i>op</i>(<i>s</i>, <i>data</i>, <i>elem</i>).
This transformation is expanded by <b>BOOST_PP_SEQ_TRANSFORM</b> for each
element in <i>seq</i> with the next available <b>BOOST_PP_SEQ_FOLD_LEFT</b> fold
step, the auxiliary <i>data</i>, and the current element in <i>seq</i>.
</dd>
<dt>data</dt>
<dd>
Auxiliary data passed to <i>pred</i>.
</dd>
<dt>seq</dt>
<dd>
The <i>seq</i> to be transformed.
</dd>
</dl>
<h4>
Remarks
</h4>
<div>
This macro expands <i>op</i> for each element in <i>seq</i>. It builds a
new <i>seq</i> out of the results of each call. If, for example, <i>seq</i>
is (<i>a</i>)(<i>b</i>)(<i>c</i>), this macro expands to...
<div>
(<i>op</i>(<i>d</i>, <i>data</i>, <i>a</i>))(<i>op</i>(<i>d</i>, <i>data</i>, <i>b</i>))(<i>op</i>(<i>d</i>,
<i>data</i>, <i>c</i>))
</div>
