This function is equivalent to C strtok. Input sequence is split into tokens, separated by separators. Separators are given by means of the predicate.</p> <p>Each part is copied and added as a new element to the output container. Thus the result container must be able to hold copies of the matches (in a compatible structure like std::string) or a reference to it (e.g. using the iterator range class). Examples of such a container are <code class="computeroutput">std::vector<std::string></code> or <code class="computeroutput">std::list<boost::iterator_range<std::string::iterator>></code> </p> <p> </p> <div class="note"><table border="0" summary="Note"> <tr> <td rowspan="2" align="center" valign="top" width="25"><img alt="[Note]" src="../../../../doc/src/images/note.png"></td> <th align="left">Note</th> </tr> <tr><td align="left" valign="top"><p>Prior content of the result will be overwritten.</p></td></tr> </table></div> <p> </p> <div class="note"><table border="0" summary="Note"> <tr> <td rowspan="2" align="center" valign="top" width="25"><img alt="[Note]" src="../../../../doc/src/images/note.png"></td> <th align="left">Note</th> </tr> <tr><td align="left" valign="top"><p>This function provides the strong exception-safety guarantee </p></td></tr> </table></div> <p> </p> <div class="variablelist"><table border="0" class="variablelist compact"> <colgroup> <col align="left" valign="top"> <col> </colgroup> <tbody> <tr> <td><p><span class="term">Parameters:</span></p></td> <td><div class="variablelist"><table border="0" class="variablelist compact"> <colgroup> <col align="left" valign="top"> <col> </colgroup> <tbody> <tr> <td><p><span class="term"><code class="computeroutput">Input</code></span></p></td> <td><p>A container which will be searched. </p></td> </tr> <tr> <td><p><span class="term"><code class="computeroutput">Pred</code></span></p></td> <td><p>A predicate to identify separators.
