10 if (NULL hServiceMgr){
11 printf(OpenSCManager() failed : %d \n, GetLastError());
12 goto BeforeLeave;
13 bRet FALSE;
14 }
15 else{
16 printf(OpenSCManager() OK!\n);
17 }
18 //创建驱动所对应的服务
19 hServiceDDK CreateService(hServiceMgr,
20 lpszDriverName,
21 lpszDriverName,
22 SERVICE_ALL_ACCESS,
23 SERVICE_KERNEL_DRIVER,
24 SERVICE_DEMAND_START,
25 SERVICE_ERROR_IGNORE,
26 szDriverImagePath,
27 NULL, NULL, NULL, NULL, NULL);
28
29 DWORD dwRtn;
30 if (NULL hServiceDDK){
31 dwRtn GetLastError();
32 if (dwRtn ! ERROR_IO_PENDING dwRtn ! ERROR_SERVICE_EXISTS){
33 printf(CreateService failed:%d!\n, dwRtn);
34 bRet FALSE;
35 goto BeforeLeave;
36 }
37 else{
38 printf(CreateService failed:ERROR_IO_PENDING or ERROR_SERVICE_EXISTS\n);
39 }
40 //创建失败说明服务已经存在直接打开即可
41 hServiceDDK OpenService(hServiceMgr, lpszDriverName, SERVICE_ALL_ACCESS);
42 if (NULL hServiceDDK){
43 dwRtn GetLastError();
44 printf(OpenService() failed:%d!\n, dwRtn);
45 bRet FALSE;
46 goto BeforeLeave;
47 }
48 else{
49 printf(OpenService OK!\n);
50 }
51 }
52 else{
53 printf(CreateService OK!\n);
54 }
55
56 //创建服务成功开启此服务
57 bRet StartService(hServiceDDK, NULL, NULL);
58 if (!bRet){
59 dwRtn GetLastError();
60 if (dwRtn ! ERROR_IO_PENDING dwRtn ! ERROR_SERVICE_ALREADY_RUNNING){
61 printf(StartService failed:%d!\n, dwRtn);
62 bRet FALSE;
63 goto BeforeLeave;
64 }
65 else{
66 if (ERROR_IO_PENDING dwRtn){
67 printf(StartService() failed:ERROR_IO_PENDING);
68 bRet FALSE;
69 goto BeforeLeave;
70 }
71 else{
72 printf(StartService() failed :ERROR_SERVICE_ALREADY_RUNNING);
73 bRet TRUE;
74 goto BeforeLeave;
75 }
76 }
77 }
78 bRet TRUE;
79 BeforeLeave:
80 if (hServiceDDK){
81 CloseServiceHandle(hServiceDDK);
82 }
83 if (hServiceMgr){
84 CloseServiceHandle(hServiceMgr);
85 }
86 return bRet;
87 } UnLoadNTDriver卸载驱动主要代码流程如下 代码如下 1 BOOL UnloadNTDriver(char*szSvrName){2 BOOL bRet FALSE;3 SC_HANDLE hServiceMgr NULL;4 SC_HANDLE hServiceDDK NULL;5 hServiceMgr OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);6 if (NULL hServiceMgr){7 printf(OpenSCManager() failed : %d \n, GetLastError());8 goto BeforeLeave;9 bRet FALSE;
10 }
11 else{
12 printf(OpenSCManager() OK!\n);
13 }
14 hServiceDDK OpenService(hServiceMgr, szSvrName, SERVICE_ALL_ACCESS);
15 if (NULL hServiceDDK){
16 printf(OpenService() failed :%d\n, GetLastError());
17 bRet FALSE;
18 goto BeforeLeave;
19 }
20 else{
21 printf(OpenService() OK!\n);
22 }
23 SERVICE_STATUS SvrSta;
24 //停止驱动程序
25 if (!ControlService(hServiceDDK, SERVICE_CONTROL_STOP, SvrSta)){
26 printf(ControlService() failed:%d\n, GetLastError());
27 }
28 else{
29 printf(ControlService() OK!\n);
30 }
31 //动态卸载驱动程序
32 if (!DeleteService(hServiceDDK)){
33 printf(DeleteService() failed:%d\n, GetLastError());
34 }
35 else{
36 printf(DeleteService() OK!\n);
37 }
38 bRet TRUE;
39
40 BeforeLeave:
41 if (hServiceDDK){
42 CloseServiceHandle(hServiceDDK);
43 }
44 if (hServiceMgr){
45 CloseServiceHandle(hServiceMgr);
46 }
47 return bRet;
48 } 安装和卸载驱动 注意这里的驱动名称和路径应该设置为 运行成功 转载于:https://www.cnblogs.com/predator-wang/p/5514107.html
