To Work With A Memory-mapped File
A memory-mapped file comprises the contents of a file in virtual memory. This mapping between a file and memory area permits an utility, including a number of processes, to switch the file by studying and writing directly to the memory. You should utilize managed code to entry memory-mapped information in the same way that native Windows features entry Memory Wave App-mapped files, as described in Managing Memory-Mapped Files. Persisted files are memory-mapped information that are related to a source file on a disk. When the last course of has finished working with the file, the information is saved to the source file on the disk. These memory-mapped files are appropriate for working with extraordinarily giant source recordsdata. Non-persisted information are memory-mapped files that are not associated with a file on a disk. When the last process has finished working with the file, the data is lost and the file is reclaimed by garbage collection. These recordsdata are suitable for creating shared memory for inter-process communications (IPC).
Memory-mapped information will be shared across multiple processes. Processes can map to the identical memory-mapped file by utilizing a standard identify that is assigned by the method that created the file. To work with a memory-mapped file, you need to create a view of the whole memory-mapped file or part of it. You may as well create multiple views to the identical a part of the memory-mapped file, thereby creating concurrent memory. For two views to stay concurrent, they have to be created from the same memory-mapped file. Multiple views may even be obligatory if the file is greater than the scale of the application's logical memory space accessible for memory mapping (2 GB on a 32-bit pc). There are two forms of views: stream access view and random entry view. Use stream entry views for sequential access to a file; that is really helpful for non-persisted files and IPC. Random entry views are most well-liked for working with persisted recordsdata. Memory-mapped files are accessed via the operating system's memory manager, so the file is routinely partitioned into quite a few pages and accessed as needed. You do not have to handle the memory management yourself. The next illustration reveals how multiple processes can have a number of and overlapping views to the identical memory-mapped file at the same time. The following desk gives a guide for using memory-mapped file objects and their members. You can specify access rights for opening an existing memory-mapped file by using the OpenExisting methods that take an MemoryMappedFileRights as a parameter. In addition, you'll be able to include a MemoryMappedFileSecurity object that accommodates predefined entry guidelines. To use new or modified entry rules to a memory-mapped file, use the SetAccessControl methodology. To retrieve entry or audit rules from an existing file, use the GetAccessControl methodology.
