|
</pre></blockquote><p>
|
|
This function is used to finalize an iterator allocated with
|
|
<a href="../session/sqlite3changeset_start.html">sqlite3changeset_start()</a>.</p>
|
|
|
|
<p>This function should only be called on iterators created using the
|
|
<a href="../session/sqlite3changeset_start.html">sqlite3changeset_start()</a> function. If an application calls this
|
|
function with an iterator passed to a conflict-handler by
|
|
<a href="../session/sqlite3changeset_apply.html">sqlite3changeset_apply()</a>, <a href="../rescode.html#misuse">SQLITE_MISUSE</a> is immediately returned and the
|
|
call has no effect.</p>
|
|
|
|
<p>If an error was encountered within a call to an sqlite3changeset_xxx()
|
|
function (for example an <a href="../rescode.html#corrupt">SQLITE_CORRUPT</a> in <a href="../session/sqlite3changeset_next.html">sqlite3changeset_next()</a> or an
|
|
<a href="../rescode.html#nomem">SQLITE_NOMEM</a> in <a href="../session/sqlite3changeset_new.html">sqlite3changeset_new()</a>) then an error code corresponding
|
|
to that error is returned by this function. Otherwise, SQLITE_OK is
|
|
returned. This is to allow the following pattern (pseudo-code):</p>
|
|
|
|
<p><pre>
|
|
sqlite3changeset_start();
|
|
while( SQLITE_ROW==sqlite3changeset_next() ){
|
|
// Do something with change.
|
|
}
|
|
rc = sqlite3changeset_finalize();
|
|
if( rc!=SQLITE_OK ){
|
|
// An error has occurred
|
|
}
|
|
</pre>
