my_bool mysql_rollback(MYSQL *mysql)
Description
Rolls back the current transaction.
As of MySQL 5.0.3, the action of this function is subject to the value of the completion_type system variable. In particular, if the value of completion_type is 2, the server performs a release after terminating a transaction and closes the client connection. The client program should call mysql_close() to close the connection from the client side.
Return Values
Zero if successful. Non-zero if an error occurred.
Errors
None.
就是没有看明白到底应该怎么用这个函数呢
