</pre></blockquote><p>
|
|
This function may only be used with iterators created by the function
|
|
<a href="../session/sqlite3changeset_start.html">sqlite3changeset_start()</a>. If it is called on an iterator passed to
|
|
a conflict-handler callback by <a href="../session/sqlite3changeset_apply.html">sqlite3changeset_apply()</a>, SQLITE_MISUSE
|
|
is returned and the call has no effect.</p>
|
|
|
|
<p>Immediately after an iterator is created by sqlite3changeset_start(), it
|
|
does not point to any change in the changeset. Assuming the changeset
|
|
is not empty, the first call to this function advances the iterator to
|
|
point to the first change in the changeset. Each subsequent call advances
|
|
the iterator to point to the next change in the changeset (if any). If
|
|
no error occurs and the iterator points to a valid change after a call
|
|
to sqlite3changeset_next() has advanced it, SQLITE_ROW is returned.
|
|
Otherwise, if all changes in the changeset have already been visited,
|
|
SQLITE_DONE is returned.</p>
|
|
|
|
<p>If an error occurs, an SQLite error code is returned. Possible error
|
|
codes include SQLITE_CORRUPT (if the changeset buffer is corrupt) or
|
|
SQLITE_NOMEM.
