C++使用事件信号SetEventt和ResetEvent实现线程同步

#include #include using namespace std; HANDLE gEvent;DWORD WINAPI Fuc1(LPVOID lpParam);DWORD WINAPI Fuc2(LPVOID lpParam); int tick = 0; DWORD __stdcall Fuc1(LPVOID lpParam){ WaitForSingleObject(gEvent, INFINITE);//请求事件对象 ResetEvent(gEvent);//重置事件为无信号状态 tick += 50; cout < " << tick << endl; for (size_t i = 0; i < 10; i++) { cout <<"f1:" << i << endl; } SetEvent(gEvent);//设置为有信号状态 return 0;} DWORD __stdcall Fuc2(LPVOID lpParam){ WaitForSingleObject(gEvent, INFINITE);//请求事件对象 ResetEvent(gEvent);//重置事件为无信号状态 tick += 50; cout < " << tick << endl; for (size_t i = 0; i < 10; i++) { cout <<"f2:" << i << endl; } SetEvent(gEvent);//设置为有信号状态 return 0;} int main(){ gEvent = CreateEvent(NULL, FALSE, false, NULL); if (gEvent) { SetEvent(gEvent); } HANDLE t1, t2; t1 = CreateThread(NULL, 0, Fuc1, NULL, 0, NULL); t2 = CreateThread(NULL, 0, Fuc2, NULL, 0, NULL); while (true) { } CloseHandle(t1); CloseHandle(t2); return 0;}
