| 术语 | getmappedfilename |
| 释义 | GetMappedFileName 语法： C++ DWORD WINAPI GetMappedFileName( __in HANDLE hProcess, __in LPVOID lpv, __out LPTSTR lpFilename, __in DWORD nSize ); GetMappedFileName功能 检查是否指定的地址是在一个内存映射到指定的进程地址空间的文件。如果是这样，该函数返回的内存的名称映射文件。 参数 hProcess [in] 句柄的进程。句柄必须有PROCESS_QUERY_INFORMATION和PROCESS_VM_READ访问权限。有关更多信息，请参见过程的安全性和访问权限。 线性变参数 [in] 地址被验证。 lpFilename [out] A到接收缓冲区的内存的名称映射文件到该处理线性变参数指定的指针所属。 nSize [in] 该lpFilename缓冲区的大小，以字符。 返回值 如果函数成功，返回值指定了复制到缓冲区的字符串的长度，以字符。 如果函数失败，返回值是零。为了获得更多错误信息，调用GetLastError。 备注 与PSAPI版本的Windows 7和Windows Server 2008 R2的2起，这个函数被定义为K32GetMappedFileName在Psapi.h和Kernel32.lib和Kernel32.dll出口。但是，您应该始终作为GetMappedFileName调用这个函数。为了确保对程序将运行在Windows的早期版本的符号的正确决议，添加Psapi.lib到TARGETLIBS宏和编译程序与- DPSAPI_VERSION = 1。 实例 有关示例，请参见获取来自文件处理文件名。 要求： 最低支持：client－Windows 2000专业版 最低支持server－Windows 2000服务器 HeaderPsapi.h LibraryKernel32.lib在Windows 7和Windows Server 2008 R2的Psapi.lib在Windows Server 2008，Windows Vista中的Windows Server 2003，和Windows XP/2000 DLLKernel32.dll在Windows 7和Windows Server 2008 R2的Psapi.dll在Windows Server 2008，Windows Vista中的Windows Server 2003，和Windows XP/2000 Unicode和ANSI namesGetMappedFileNameW(Unicode)和GetMappedFileNameA(ANSI)的 参见 EnumProcesses 内存映射文件信息 PSAPI函数 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＝＝GetMappedFileName Function Checks whether the specified address is within a memory-mapped file in the address space of the specified process. If so, the function returns the name of the memory-mapped file. Syntax C++ DWORD WINAPI GetMappedFileName( __in HANDLE hProcess, __in LPVOID lpv, __out LPTSTR lpFilename, __in DWORD nSize ); Parameters hProcess [in] A handle to the process. The handle must have the PROCESS_QUERY_INFORMATION and PROCESS_VM_READ access rights. For more information, see Process Security and Access Rights . lpv [in] The address to be verified. lpFilename [out] A pointer to the buffer that receives the name of the memory-mapped file to which the address specified by lpv belongs. nSize [in] The size of the lpFilename buffer, in characters. Return Value If the function succeeds, the return value specifies the length of the string copied to the buffer, in characters. If the function fails, the return value is zero. To get extended error information, call GetLastError . Remarks Starting with PSAPI version 2 for Windows 7 and Windows Server 2008 R2, this function is defined as K32GetMappedFileName in Psapi.h and exported in Kernel32.lib and Kernel32.dll. However, you should always call this function as GetMappedFileName. To ensure correct resolution of symbols for programs that will run on earlier versions of Windows, add Psapi.lib to the TARGETLIBS macro and compile the program with –DPSAPI_VERSION=1.
