NT驱动程序的加载:
1:为NT驱动创建新的服务.
2:开启此项服务
3:关闭此项服务
4:删除NT驱动创建的服务
(1)打开SCM管理器
SC_HANDLE WINAPI OpenSCManager(
__in LPCTSTR lpMachineName,//计算机名称.NULL或者空表示本机
__in LPCTSTR lpDatabaseName,//SCM数据库名称.NULL表示使用缺省数据库
__in DWORD dwDesiredAccess //使用权限.一般为SC_MANAGER_ALL_ACCESS
);
成功返回SCM管理器句柄.否则返回NULL
(2)创建服务
SC_HANDLE WINAPI CreateService(
__in SC_HANDLE hSCManager,//OpenSCManager打开的句柄
__in LPCTSTR lpServiceName,//服务名称.SCM管理器中看到的服务名称
__in LPCTSTR lpDisplayName,
__in DWORD dwDesiredAccess,//打开权限.一般为SERVICE_ALL_ACCESS
__in DWORD dwServiceType, //服务类型(文件系统驱动/普通驱动程序/驱动自加载/)
__in DWORD dwStartType, //启动类型
__in DWORD dwErrorControl, //错误控制码
__in LPCTSTR lpBinaryPathName,//服务程序或者驱动程序的路径
__in LPCTSTR lpLoadOrderGroup,//服务属于哪个用户组
__out LPDWORD lpdwTagId,
__in LPCTSTR lpDependencies, //所依赖的服务的名称
__in LPCTSTR lpServiceStartName, //用户帐户名称
__in LPCTSTR lpPassword //用户口令
);
(3)打开服务
SC_HANDLE WINAPI OpenService(
__in SC_HANDLE hSCManager, //SCM管理器句柄
__in LPCTSTR lpServiceName, //服务名称
__in DWORD dwDesiredAccess //访问权限.一般为SC_MANAGER_ALL_ACCESS
);
(4)控制服务
BOOL WINAPI ControlService(
__in SC_HANDLE hService, //服务句柄
__in DWORD dwControl, //控制码
__out LPSERVICE_STATUS lpServiceStatus //指向一个SERVICE_STATUS 结构体,来接收最后的服务信息
);
(5)关闭SCM管理器
BOOL WINAPI CloseServiceHandle(
__in SC_HANDLE hSCObject
);
