When memory mapping files in a POSIX system, do we need to keep the file-descriptor open till we\'re done with the mmaped memory block (and close it after we munmap) or can (should?) we close the file
My requirement is to provide a shared memory file between 32 bit and 64 bit processes. This file can be created by any of the process depends upon who comes first.
Is there an api to do memory mapping, just l开发者_运维技巧ike mmap() on linux?Depends on what exactly you want to use it for. If you want to map existing files into memory, that\'s supported with
I need to know the feasibility of \"mmaping\" a virtualmemory and loading binary code into it and execute the binary code. The binary code (presented as shared library) may be mach format or elf forma
I have a device driver that uses buffers in RAM that I want the user to be able to map to user space. I have read http://lwn.net/images/pdf/LDD3/ch15.pdf which talks about using nopages, but the examp
I have a problem that was described in multiple threads concerning memory mapping and a growing memory consumption under Linux.
If I read and write a single file using normal IO APIs, writes are guaranteed to be atomic on a per-block basis. That is, if my write only modifies a single block, the operating system guarantees that
I\'m working on software to control a mmap\'d device on an embedded ARM system, but have run into a few situations where the debugging and development tools available haven\'t been sufficient. i.e. In
I have some code (which I cannot change) that I need to get working in a native Win32 environment.This code calls mmap() and munmap(), so I have created those functions using CreateFileMapping(), MapV
I\'m running into an issue with GDB and some buffers allocated in kernel space.The buffers are allocated by a kernel module that is supposed to allocate contiguous blocks of memory, and then memory ma
