| 术语 | openprocess |
| 释义 | OpenProcess 语法： C++ HANDLE WINAPI OpenProcess( __in DWORD dwDesiredAccess, __in BOOL bInheritHandle, __in DWORD dwProcessId ); OpenProcess函数 打开一个现有的本地处理对象。 参数 dwDesiredAccess [in] 对这一进程对象访问。这探视权，对检查的过程中的安全描述符。此参数可以是一个或更多的进程访问的权利。 如果调用方已使SeDebugPrivilege特权，请求授予访问权限，不论安全描述符的内容。 bInheritHandle [in] 如果该值为TRUE，进程创建的这一进程将继承处理。否则，该进程不会继承此处理。 dwProcessId [in] 当地的进程标识符被打开。 如果指定的进程是系统进程(00000000)，该功能失败，最后错误代码是ERROR_INVALID_PARAMETER。如果指定的进程是空闲进程或CSRSS中的一个过程，这个函数失败，最后错误代码是ERROR_ACCESS_DENIED，因为他们的访问限制阻止他们打开用户级代码。 返回值 如果函数成功，返回值是一个开放的句柄指定的进程。 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 要打开句柄到另一个地方的过程，并获得完全访问权，您必须启用SeDebugPrivilege特权。有关更多信息，请参阅更改权限的令牌。 在处理返回的OpenProcess函数可以在任何函数，需要处理的进程，如等待函数，使用，提供相应的访问权限的要求。 当您完成与处理，一定要关闭它使用CloseHandle函数。 实例 有关示例，请参阅以快照和浏览过程。 要求： 最低支持：client－Windows 2000专业版 最低支持server－Windows 2000服务器 HeaderWinbase.h(头文件：winuser.h) LibraryKernel32.lib DLLKernel32.dll 参见 AssignProcessToJobObject CloseHandle CreateProcess的 CreateRemoteThread的 DuplicateHandle GetCurrentProcess GetCurrentProcessId GetExitCodeProcess GetModuleFileNameEx GetPriorityClass 进程和线程函数 过程 ReadProcessMemory的 SetPriorityClass SetProcessWorkingSetSize TerminateProcess VirtualProtectEx WriteProcessMemory的 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＝＝OpenProcess Function Opens an existing local process object. Syntax C++ HANDLE WINAPI OpenProcess( __in DWORD dwDesiredAccess, __in BOOL bInheritHandle, __in DWORD dwProcessId ); Parameters dwDesiredAccess [in] The access to the process object. This access right is checked against the security descriptor for the process. This parameter can be one or more of the process access rights . If the caller has enabled the SeDebugPrivilege privilege, the requested access is granted regardless of the contents of the security descriptor. bInheritHandle [in] If this value is TRUE, processes created by this process will inherit the handle. Otherwise, the processes do not inherit this handle. dwProcessId [in] The identifier of the local process to be opened. If the specified process is the System Process (0x00000000), the function fails and the last error code is ERROR_INVALID_PARAMETER. If the specified process is the Idle process or one of the CSRSS processes, this function fails and the last error code is ERROR_ACCESS_DENIED because their access restrictions prevent user-level code from opening them. Return Value If the function succeeds, the return value is an open handle to the specified process. If the function fails, the return value is NULL. To get extended error information, call GetLastError . Remarks To open a handle to another local process and obtain full access rights, you must enable the SeDebugPrivilege privilege. For more information, see Changing Privileges in a Token . The handle returned by the OpenProcess function can be used in any function that requires a handle to a process, such as the wait functions , provided the appropriate access rights were requested. When you are finished with the handle, be sure to close it using the CloseHandle function. Examples For an example, see Taking a Snapshot and Viewing Processes .
