- 以id创建事件
char name[] = "myevent";
HANDLE event = CreateEventA(NULL, FALSE, FALSE, name); - 设置事件
SetEvent(event);
- 关闭事件
CloseHandle(event);
- 另一个进程打开事件
HANDLE event = OpenEventA(EVENT_ALL_ACCESS, TRUE, name);//打开事件
- 然后等待事件
DWORD res = WaitForSingleObject(event, );
- 等待结果
case WAIT_OBJECT_0:
printf("收到信号-------");
break;
case WAIT_TIMEOUT:
printf("超时没有收到-------");
break;
case WAIT_ABANDONED:
printf("另外一个进程意外终止-------");
break;
