Memory-Mapped檔案資訊 發行項 2023/06/13 4 位參與者 意見反應 記憶體對應檔案 (或檔案對應) 是將檔案的內容與進程虛擬位址空間的一部分產生關聯的結果。 它可用來在兩個或多個進程之間共用檔案或記憶體。 GetMappedFileName函式會接收進程控制碼和位址的指標做為輸入。 如果位址位於進程的虛擬位址空間中的記憶...
Looks at the evolution of memory management in Windows, especially the new mapped-file functions designed for the 32-bit flat, paged memory model. Addressing memory using page tables; Flat-memory model; Win32 memory management application program interface (API); Data types in Win16 and Win32;...
FILE_MAP_ALL_ACCESS A read/write view of the file is mapped. The file mapping object must have been created with PAGE_READWRITE or PAGE_EXECUTE_READWRITE protection. When used with the MapViewOfFileEx function, FILE_MAP_ALL_ACCESS is equivalent to FILE_MAP_WRITE. FILE_MAP_READ A read...
paging file. This requires that a name for the memory-mapped object get passed as the last parameter. } MapHandle := CreateFileMapping(DWord(-1), nil, PAGE_READWRITE, 0, Size, cMMFileName); if MapHandle = 0 then RaiseLastWin32Error; { Now map the data to the calling process's add...
by reading and writing directly to the memory. Starting with the .NET Framework version 4, you can use managed code to access memory-mapped files in the same way that native Windows functions access memory-mapped files, as described inManaging Memory-Mapped Files in Win32in the MSDN Library....

FILE_MAP_ALL_ACCESS A read/write view of the file is mapped. The file mapping object must have been created with PAGE_READWRITE protection. When used with MapViewOfFileFromApp, FILE_MAP_ALL_ACCESS is equivalent to FILE_MAP_WRITE. FILE_MAP_READ A read-only view of the file is m...
Window offers three groups of functions for managing memory in applications: memory-mapped file functions, heap memory functions, and virtual-memory functions. Figure 1. The Windows API provides different levels of memory management for versatility in application programming. ...
包含有关内存区域的信息。 内存区域是使用内存分配函数(例如 VirtualAlloc 或MapViewOfFile)创建的单个分配。语法C++ 复制 typedef struct WIN32_MEMORY_REGION_INFORMATION { PVOID AllocationBase; ULONG AllocationProtect; union { ULONG Flags; struct { ULONG Private : 1; ULONG MappedDataFile : 1; ULONG ...
利用文件与内存空间之间的映射,应用程序(包括多个进程)可以通过直接在内存中进行读写来修改文件。.NET Framework 4 用托管代码按照本机Windows函数访问内存映射文件的方式来访问内存映射文件,管理 Win32 中的内存映射文件。 有两种类型的内存映射文件: 持久内存映射文件 ...
