CSoD:Colorful Screen of Death

****************************************************
1.使用
1.使用前请加载好驱动！
2.本驱动会创建一个名为CSoD的设备，请使用CreateFile打开之以通信（独占设备，同时只能打开一次）
（HANDLE hDevice = CreateFileW(L"\\\\.\\CSoD", GENERIC_ALL, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);）
3.然后，请创建一个“CSoD_DATA”（在ControlCode.h中）类型的变量，并初始化之（成员解释请看注释）
（
CSoD_DATA Data = { 0 };
Data.BackColor = BV_COLOR_BLACK;
Data.TextColor = BV_COLOR_WHITE;
）
4.使用DeviceIoControl传入这个变量，并使用CTL_DO_CSoD控制码
（
BOOL bRet = DeviceIoControl(hDevice, CTL_DO_CSoD, &Data, sizeof(Data), NULL, 0, &dwReturned, NULL);
）
