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.

C 的没有用过。
如果不用这个函数，直接发送 begin,rollback,commit 之类的 sql 查询应该也是可以的吧。
