[問題] 結構指標的問題
開發平台(Platform): (Ex: VC++, GCC, Linux, ...)
gcc
額外使用到的函數庫(Library Used): (Ex: OpenGL, ...)
程式碼：
typedef struct notify_buildreq_tag {
u32 id;
u32 state;} NOTIFY_BUILDREQ;
typedef struct notify_process_buildreq_result_tag {
u8 result;} NOTIFY_BUILDREQ_RESULT;
typedef struct notify_process_tag {
u32 state;} NOTIFY_PROCESS;
typedef struct notify_process_result_tag {
u8 result; u8 done;} NOTIFY_PROCESS_RESULT;
typedef struct notify_data_tag {
u8 type;
union {
NOTIFY_BUILDREQ bldReq;
NOTIFY_BUILDREQ_RESULT bldReqResult;
NOTIFY_PROCESS process;
NOTIFY_PROCESS_RESULT processResult;
} u;
u32 length; // length of the data that follows
uint32 addr_length;
char addr[16];
} NOTIFY_DATA;
main(){
NOTIFY_DATA * recvNotify;
recvNotify = (NOTIFY_DATA *) buf;
dprintf("[test2.1] ==> %x\n",(recvNotify));
dprintf("[test2] ==> %x\n",(recvNotify + 0x24));
}
餵入的資料(Input)：
預期的正確結果(Expected Output)：
倆著應該只差offset 0x24
錯誤結果(Wrong Output)：
offset 510??
[test2.1] ==> 814361e8
[test2] ==> 814366f8
問題
為什麼兩者的差距不適0x24?
補充說明(Supplement)：
