reactos操作系统实现(68)

前端之家收集整理的这篇文章主要介绍了reactos操作系统实现(68)前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

前面介绍怎么样调用动态连接库里的InstallReactOS函数,下面就来分析这个函数代码,看看这个函数是怎么运行向导界面,又做了些什么样的工作。如下:

#001 DWORD WINAPI

#002 InstallReactOS(HINSTANCE hInstance)

#003 {

#004 TCHAR szBuffer[MAX_PATH];

#005 DWORD LastError;

#006 HANDLE token;

#007 TOKEN_PRIVILEGES privs;

#008

ReactOS目录里创建安装的LOG文件

#009 InitializeSetupActionLog(FALSE);

#010 LogItem(SYSSETUP_SEVERITY_INFORMATION,L"Installing ReactOS");

#011

初始化注册配置相关项。

#012 if (!InitializeProfiles())

#013 {

#014 DebugPrint("InitializeProfiles() Failed");

#015 return 0;

#016 }

#017

创建桌面、菜单文件关联的快捷方式。

#018 if (!CreateShortcuts())

#019 {

#020 DebugPrint("InitializeProfiles() Failed");

#021 return 0;

#022 }

#023

创建安全相关的帐号管理。

#024 /* Initialize the Security Account Manager (SAM) */

#025 if (!SamInitializeSAM())

#026 {

#027 DebugPrint("SamInitializeSAM() Failed!");

#028 return 0;

#029 }

#030

为安装用户提供一个随便的电脑名称

#031 /* Create the semi-random Domain-SID */

#032 if (!CreateRandomSid(&DomainSid))

#033 {

#034 DebugPrint("Domain-SID creation Failed!");

#035 return 0;

#036 }

#037

把这个电脑名称保存到注册表。

#038 /* Set the Domain SID (aka Computer SID) */

#039 if (!SamSetDomainSid(DomainSid))

#040 {

#041 DebugPrint("SamSetDomainSid() Failed!");

#042 RtlFreeSid(DomainSid);

#043 return 0;

#044 }

#045

#046 /* Append the Admin-RID */

#047 AppendRidToSid(&AdminSid,DomainSid,DOMAIN_USER_RID_ADMIN);

#048

创建管理员帐号。

#049 /* Create the Administrator account */

#050 if (!SamCreateUser(L"Administrator",L"",AdminSid))

#051 {

#052 /* Check what the error was.

#053 * If the Admin Account already exists,then it means Setup

#054 * wasn't allowed to finish properly. Instead of rebooting

#055 * and not completing it,let it restart instead

#056 */

#057 LastError = GetLastError();

#058 if (LastError != ERROR_USER_EXISTS)

#059 {

#060 DebugPrint("SamCreateUser() Failed!");

#061 RtlFreeSid(AdminSid);

#062 RtlFreeSid(DomainSid);

#063 return 0;

#064 }

#065 }

#066

#067 RtlFreeSid(AdminSid);

#068 RtlFreeSid(DomainSid);

#069

管理员的帐号登录

#070 /* ROS HACK,as long as NtUnloadKey is not implemented */

#071 {

#072 NTSTATUS Status = NtUnloadKey(NULL);

#073 if (Status == STATUS_NOT_IMPLEMENTED)

#074 {

#075 /* Create the Administrator profile */

#076 PROFILEINFOW ProfileInfo;

#077 HANDLE hToken;

#078 BOOL ret;

#079 #define logoN32_logoN_NETWORK 3

#080 ret = logonUserW(L"Administrator",logoN32_logoN_NETWORK,logoN32_PROVIDER_DEFAULT,&hToken);

#081 if (!ret)

#082 {

#083 DebugPrint("logonUserW() Failed!");

#084 return 0;

#085 }

#086 ZeroMemory(&ProfileInfo,sizeof(PROFILEINFOW));

#087 ProfileInfo.dwSize = sizeof(PROFILEINFOW);

#088 ProfileInfo.lpUserName = L"Administrator";

#089 ProfileInfo.dwFlags = PI_NOUI;

#090 LoadUserProfileW(hToken,&ProfileInfo);

#091 CloseHandle(hToken);

#092 }

#093 else

#094 {

#095 DPRINT1("ROS HACK not needed anymore. Please remove it/n");

#096 }

#097 }

#098 /* END OF ROS HACK */

#099

创建系统工作的临时目录。

#100 CreateTempDir(L"TEMP");

#101 CreateTempDir(L"TMP");

#102

创建system目录。

#103 if (GetWindowsDirectory(szBuffer,sizeof(szBuffer) / sizeof(TCHAR)))

#104 {

#105 PathAddBackslash(szBuffer);

#106 _tcscat(szBuffer,_T("system"));

#107 CreateDirectory(szBuffer,NULL);

#108 }

#109

根据syssetup.inf文件来安装相应的组件,还安装PNP管理器。

#110 if (!CommonInstall())

#111 return 0;

#112

初始化让用户选择输入参数的向导界面。

#113 InstallWizard();

#114

关闭syssetup.inf文件

#115 SetupCloseInfFile(hSysSetupInf);

设置系统安装的类型。

#116 SetSetupType(0);

#117

#118 LogItem(SYSSETUP_SEVERITY_INFORMATION,L"Installing ReactOS done");

关闭安装的LOG文件

#119 TerminateSetupActionLog();

#120

获取关闭系统的特权。

#121 /* Get shutdown privilege */

#122 if (! OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES,&token))

#123 {

#124 DebugPrint("OpenProcessToken() Failed!");

#125 return 0;

#126 }

#127 if (!LookupPrivilegeValue(

#128 NULL,

#129 SE_SHUTDOWN_NAME,

#130 &privs.Privileges[0].Luid))

#131 {

#132 DebugPrint("LookupPrivilegeValue() Failed!");

#133 return 0;

#134 }

#135 privs.PrivilegeCount = 1;

#136 privs.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

#137 if (AdjustTokenPrivileges(

#138 token,

#139 FALSE,

#140 &privs,

#141 0,

#142 (PTOKEN_PRIVILEGES)NULL,

#143 NULL) == 0)

#144 {

#145 DebugPrint("AdjustTokenPrivileges() Failed!");

#146 return 0;

#147 }

#148

退系统,并重新启动。

#149 ExitWindowsEx(EWX_REBOOT,0);

#150 return 0;

#151}
