To Work with a Memory-mapped File

A memory-mapped file comprises the contents of a file in digital memory. This mapping between a file and memory area enables an application, together with a number of processes, to switch the file by reading and writing directly to the memory. You can use managed code to access memory-mapped files in the identical manner that native Home windows functions access memory-mapped recordsdata, as described in Managing Memory-Mapped Recordsdata. Persisted recordsdata are memory-mapped information that are associated with a source file on a disk. When the final process has completed working with the file, the data is saved to the source file on the disk. These memory-mapped files are suitable for working with extremely massive supply information. Non-persisted information are Memory Wave-mapped information that are not associated with a file on a disk. When the final process has finished working with the file, the information is lost and the file is reclaimed by rubbish assortment. These recordsdata are appropriate for creating shared memory for inter-course of communications (IPC).

Memory-mapped files may be shared across a number of processes. Processes can map to the identical memory-mapped file through the use of a typical title that's assigned by the method that created the file. To work with a memory-mapped file, you could create a view of your entire memory-mapped file or part of it. You too can create a number of views to the identical a part of the memory-mapped file, thereby creating concurrent memory. For two views to remain concurrent, they must be created from the same memory-mapped file. A number of views might even be essential if the file is larger than the dimensions of the application's logical memory house obtainable for memory mapping (2 GB on a 32-bit pc). There are two varieties of views: stream entry view and random entry view. Use stream access views for sequential access to a file; this is really helpful for non-persisted information and IPC. Random access views are preferred for working with persisted files. Memory-mapped files are accessed via the operating system's memory manager, so the file is routinely partitioned into numerous pages and accessed as wanted. You do not should handle the memory administration yourself. The following illustration reveals how a number of processes can have a number of and overlapping views to the same memory-mapped file at the identical time. The following table provides a information for utilizing Memory Wave Method-mapped file objects and their members. You may specify access rights for opening an present memory-mapped file through the use of the OpenExisting methods that take an MemoryMappedFileRights as a parameter. In addition, you may embrace a MemoryMappedFileSecurity object that comprises predefined entry rules. To apply new or modified entry guidelines to a memory-mapped file, use the SetAccessControl technique. To retrieve entry or audit rules from an existing file, use the GetAccessControl methodology.
