| 释义 | CreateWindowStation 语法： C++ HWINSTA WINAPI CreateWindowStation( __in_opt LPCTSTR lpwinsta, DWORD dwFlags, __in ACCESS_MASK dwDesiredAccess, __in_opt LPSECURITY_ATTRIBUTES lpsa ); CreateWindowStation功能 创建与调用过程窗口站对象，联营它，并将其分配给本届会议。 参数 lpwinsta [中，可选] 窗口的站名被创建。窗口站名是区分大小写，且不能包含反斜杠字符(\\)。 Administrators组的成员才允许指定一个名称。如果lpwinsta为NULL或空字符串，系统构成了调用进程的一个窗口，站名使用登录会话标识符。要获得此名称，调用GetUserObjectInformation功能。 dwFlags 如果该参数CWF_CREATE_ONLY和窗口站已经存在，调用失败。如果此标志没有被指定的窗口站已经存在，函数成功，并返回一个新的句柄现有的窗口站。 Windows XP/2000操作系统：此参数是保留，必须为零。 dwDesiredAccess [in] 的访问返回的句柄类型的窗口站。此外，您可以指定任何标准访问权限，如次数READ_CONTROL或WRITE_DAC，以及对窗口站结合特定的访问权限。有关更多信息，请参阅窗口站的安全和访问权限。 lpsa [中，可选] 一个 SECURITY_ATTRIBUTES结构，决定是否返回的句柄可以被继承的子进程的指针。如果lpsa为NULL，则句柄不能被继承。 结构的lpSecurityDescriptor成员指定一个新的窗口站的安全描述符。如果lpsa为NULL，则窗口站(并在窗口创建的任何桌面)获得一个安全描述符授予GENERIC_ALL访问所有用户。 返回值 如果函数成功，返回值是一个句柄到新创建的窗口站。如果指定的窗口站已经存在，函数成功并返回处理现有的窗口站。 如果函数失败，返回值为NULL。为了获得更多错误信息，调用GetLastError。 备注 之后，您对处理完成后，您必须调用CloseWindowStation释放处理。 要求： 最低支持：client－Windows 2000专业版 最低支持server－Windows 2000服务器 HeaderWinuser.h(头文件：winuser.h) LibraryUser32.lib DLLUser32.dll Unicode和ANSI namesCreateWindowStationW(Unicode)和CreateWindowStationA(ANSI)的 参见 CloseWindowStation GetUserObjectInformation OpenWindowStation 窗口站和桌面功能 窗口站 如果有任何问题和意见，请发送给微软(wsddocfb@microsoft.com) 生成日期：2009年8月27日 ＝＝英文原文＝＝CreateWindowStation Function Creates a window station object, associates it with the calling process, and assigns it to the current session. Syntax C++ HWINSTA WINAPI CreateWindowStation( __in_opt LPCTSTR lpwinsta, DWORD dwFlags, __in ACCESS_MASK dwDesiredAccess, __in_opt LPSECURITY_ATTRIBUTES lpsa ); Parameters lpwinsta [in, optional] The name of the window station to be created. Window station names are case-insensitive and cannot contain backslash characters (\\). Only members of the Administrators group are allowed to specify a name. If lpwinsta is NULL or an empty string, the system forms a window station name using the logon session identifier for the calling process. To get this name, call the GetUserObjectInformation function. dwFlags If this parameter is CWF_CREATE_ONLY and the window station already exists, the call fails. If this flag is not specified and the window station already exists, the function succeeds and returns a new handle to the existing window station. Windows XP/2000: This parameter is reserved and must be zero. dwDesiredAccess [in] The type of access the returned handle has to the window station. In addition, you can specify any of the standard access rights, such as READ_CONTROL or WRITE_DAC, and a combination of the window station-specific access rights. For more information, see Window Station Security and Access Rights . lpsa [in, optional] A pointer to a SECURITY_ATTRIBUTES structure that determines whether the returned handle can be inherited by child processes. If lpsa is NULL, the handle cannot be inherited. The lpSecurityDescriptor member of the structure specifies a security descriptor for the new window station. If lpsa is NULL, the window station (and any desktops created within the window) gets a security descriptor that grants GENERIC_ALL access to all users. Return Value If the function succeeds, the return value is a handle to the newly created window station. If the specified window station already exists, the function succeeds and returns a handle to the existing window station. If the function fails, the return value is NULL. To get extended error information, call GetLastError . Remarks After you are done with the handle, you must call CloseWindowStation to free the handle.
