從KProcCheck的代碼里提取出來的，不用安裝驅(qū)動程序，自己的程序里要用的時候用HANDLE openDriver(void)加載驅(qū)動，用完了void uninstallDriver(void)卸載。使用時還需自己修改，代碼不難，看下就明白了。
代碼如下：
//HANDLE openDriver(void)打開驅(qū)動建立的符號鏈接的句柄
//void uninstallDriver(void)卸載驅(qū)動，要把openDriver打開的句柄關(guān)閉才可以成功卸載
#include <windows.h>
#define DRV_NAME "DLPORTIO"http://驅(qū)動名
#define DRV_FILENAME "DLPORTIO.sys"http://驅(qū)動文件
#define STATUS_SUCCESS ((NTSTATUS)0x00000000L)
