一、用户空间宏

1. 用户空间code相关宏

{
public:
        enum {
                /* binder服务函数code从1开始 */
                FIRST_CALL_TRANSACTION = 0x00000001,
                LAST_CALL_TRANSACTION = 0x00ffffff,

                /* binder系统的code */
                PING_TRANSACTION = 0x5f504e47
                DUMP_TRANSACTION = 0x5f444d50
