SQLITE3CHANGESET_OP(3)     Library Functions Manual     SQLITE3CHANGESET_OP(3)

NAME
     sqlite3changeset_op - Obtain The Current Operation From A Changeset
     Iterator

SYNOPSIS
     int
     sqlite3changeset_op(sqlite3_changeset_iter *pIter, const char **pzTab,
         int *pnCol, int *pOp, int *pbIndirect                 );

DESCRIPTION
     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
     call to sqlite3changeset_next() must have returned SQLITE_ROW.  If this
     is not the case, this function returns SQLITE_MISUSE.

     If argument pzTab is not NULL, then *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 pnCol is not NULL, then *pnCol is set to
     the number of columns in the table affected by the change.  If
     pbIncorrect 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.  Finally, if pOp is not NULL, then *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.

     If no error occurs, SQLITE_OK is returned.  If an error does occur, an
     SQLite error code is returned.  The values of the output variables may
     not be trusted in this case.
