C++使用Windows API CreateMutex函式多執行緒程式設計

C++中也可以使用Windows 系統中對應的API函式進行多執行緒程式設計。使用CreateThread函式建立執行緒,並且可以通過CreateMutex建立一個互斥量實現執行緒間資料的同步:
#include <iostream> #include <Windows.h> using namespace std; HANDLE hMutex = NULL; //互斥量 DWORD WINAPI thread01(LPVOID lvParamter) { for (int i = 0; i < 10; i++) { WaitForSingleObject(hMutex, INFINITE); //互斥鎖 cout << "Thread 01 is working!" << endl; ReleaseMutex(hMutex); //釋放互斥鎖 } return 0; } DWORD WINAPI thread02(LPVOID lvParamter) { for (int i = 0; i < 10; i++) { WaitForSingleObject(hMutex, INFINITE); //互斥鎖 cout << "Thread 02 is working!" << endl; ReleaseMutex(hMutex); //釋放互斥鎖 } return 0; } int main() { hMutex = CreateMutex(NULL, FALSE, (LPCWSTR)"Test"); //建立互斥量 HANDLE hThread = CreateThread(NULL, 0, thread01, NULL, 0, NULL); //建立執行緒01 hThread = CreateThread(NULL, 0, thread02, NULL, 0, NULL); //建立執行緒01 CloseHandle(hThread); //關閉控制代碼 system("pause"); return 0; }
