參考看看!
abc.h: ==================== typedef struct aaa{ unsigned char Data[10]; unsigned char DataLen; unsigned int Type; }aaa_Type;
extern aaa_Type aaaTypeMsg;
abc.c: ==================== #include "abc.h" aaa_Type aaaTypeMsg; /*將static 宣告改為global
def.c ==================== #include "abc.h"
aaaTypeMsg.Data[2]=4;

我有一個檔案部分內容如下 abc.h: ==================== typedef struct aaa{ unsigned char Data[10]; unsigned char DataLen; unsigned int Type; }aaa_Type; ==================== abc.c: ==================== #include "abc.h" static aaa_Type aaaTypeMsg; ====================
現在有一個檔案def.c要用到aaaTypeMsg的內容 我在def.c裡面要如何去extern,才可以讀寫aaaTypeMsg的內容值?
