線程按指定次序輸入字符到數組的實例代碼

線程按指定次序輸入字符到數組的實例代碼。本站提示廣大學習愛好者：（線程按指定次序輸入字符到數組的實例代碼）文章只能為提供參考，不一定能成為您想要的結果。以下是線程按指定次序輸入字符到數組的實例代碼正文

標題：

有三個線程，線程1的功效就是向字符數組輸入A，線程2的功效就是向字符數組輸入B，線程2的功效就是向字符數組輸入C，請求按次序向數組賦值ABCABCABC，ABC的個數由線程函數1的參數指定。

接口解釋：

void Init();  //初始化函數

void Release(); //資本釋放函數

unsignedint__stdcall ThreadFun1(PVOID pM)  ; //線程函數1，傳入一個int類型的指針，用於初始化輸入A次數，資本須要線程釋放

unsignedint__stdcall ThreadFun2(PVOID pM)  ;//線程函數2，無參數傳入

unsignedint__stdcall ThreadFun3(PVOID pM)  ;//線程函數3，無參數傳入

char  g_write[1024]; //線程1,線程2,線程3按到次序向該數組賦值。不消斟酌數組能否越界，測試用例包管
