+Create an iterator used to iterate through the contents of a changeset.
+If successful, *pp is set to point to the iterator handle and SQLITE_OK
+is returned. Otherwise, if an error occurs, *pp is set to zero and an
+SQLite error code is returned.</p>
+
+<p>The following functions can be used to advance and query a changeset 
+iterator created by this function:</p>
+
+<p><ul>
+  <li> <a href="../session/sqlite3changeset_next.html">sqlite3changeset_next()</a>
+  <li> <a href="../session/sqlite3changeset_op.html">sqlite3changeset_op()</a>
+  <li> <a href="../session/sqlite3changeset_new.html">sqlite3changeset_new()</a>
+  <li> <a href="../session/sqlite3changeset_old.html">sqlite3changeset_old()</a>
+</ul></p>
+
+<p>It is the responsibility of the caller to eventually destroy the iterator
+by passing it to <a href="../session/sqlite3changeset_finalize.html">sqlite3changeset_finalize()</a>. The buffer containing the
+changeset (pChangeset) must remain valid until after the iterator is
+destroyed.</p>
+
+<p>Assuming the changeset blob was created by one of the
+<a href="../session/sqlite3session_changeset.html">sqlite3session_changeset()</a>, <a href="../session/sqlite3changeset_concat.html">sqlite3changeset_concat()</a> or
+<a href="../session/sqlite3changeset_invert.html">sqlite3changeset_invert()</a> functions, all changes within the changeset 
+that apply to a single table are grouped together. This means that when 
+an application iterates through a changeset using an iterator created by 
+this function, all changes that relate to a single table are visited 
+consecutively. There is no chance that the iterator will visit a change 
+the applies to table X, then one for table Y, and then later on visit 
+another change for table X.</p>
+
+<p>The behavior of sqlite3changeset_start_v2() and its streaming equivalent
+may be modified by passing a combination of
+<a href="../session/c_changesetstart_invert.html">supported flags</a> as the 4th parameter.</p>
+
+<p>Note that the sqlite3changeset_start_v2() API is still <b>experimental</b>
+and therefore subject to change.
