** The pIter argument passed to this function may either be an iterator
** passed to a conflict-handler by [sqlite3changeset_apply()], or an iterator
** created by [sqlite3changeset_start()]. In the latter case, the most recent

** is not the case, this function returns [SQLITE_MISUSE].
**
** Arguments pOp, pnCol and pzTab may not be NULL. Upon return, three
** outputs are set through these pointers:
**
** *pOp is set to one of [SQLITE_INSERT], [SQLITE_DELETE] or [SQLITE_UPDATE],
** depending on the type of change that the iterator currently points to;
**
** *pnCol is set to the number of columns in the table affected by the change; and
**
** *pzTab is set to point to a nul-terminated utf-8 encoded string containing
** the name of the table affected by the current change. The buffer remains
** valid until either sqlite3changeset_next() is called on the iterator
** or until the conflict-handler function returns.

**
** If pbIndirect is not NULL, then *pbIndirect is set to true (1) if the change
** is an indirect change, or false (0) otherwise. See the documentation for
** [sqlite3session_indirect()] for a description of direct and indirect
** changes.
