An Introduction
/dev/shm/is the next most useful directory for Linux because it's not on the hard drive, it's in memory. Therefore, under Linux, there is no need for a lot of trouble to build RAMDisk, direct use of/dev/shm/can achieve a very good optimization effect. One of the/dev/shm/to note is the capacity problem, which, under Linux, defaults to a maximum of
Dev is the initials of the device (device). /dev This directory is very important to all users. Because the directory contains all the external devices used in the Linux system. But here is not the driver for the external device, which is not the same as the Windows,dos operating system. It is actually a port to access these external devices. We can access these external devices very conveniently, and acces
reduce the file system and free the VM resources, of course, when the file is created in the dynamic allocation of VM resources. In addition, the TMPFS does not have persistence, and the data is not retained after rebooting, for obvious reasons, it is memory-based.When compiling the kernel, enable Virtual memory file system support to use Tmpfs,linux kernel to start supporting TMPFS from 2.4 onwards. The current mainstream Linux system is enabled by default TMPFS, such as Redhat.What is/

Install Gtkmm
1. First install dev-cpp
2. then install the latest gtkmm2.4 from http://www.pcpm.ucl.ac.be /~ Gustin/win32_ports/index.html
The development environment without gtk2.4 is automatically detected during the installation process, and the installation program is automatically downloaded. Note: Install both environments in the main directory of dev-cpp, for example, d:/
The device under/proc/devices/is generated by the driver, which can generate a major for mknod as the parameter.The devices under/dev/are added by mknod. You can use this device name to access the driver.The following script, scull_load, is part of the scull distribution. The user of a driver that is distributed in the form of a module can invoke such a script from the system'sRC. LocalFile or call it manually whenever the module is needed.#! /Bin/shM

TMPFS is a memory-based file system on the Linux/unix system. TMPFS can use your memory or swap partition to store files. Thus, TMPFS primarily stores staged files. It has the following 2 advantages: 1. The size of the dynamic file system. 2. Another major benefit of TMPFS is its lightning-fast speed. Because a t

There are 2 types of devices in Linux: Character devices (unbuffered and can only be accessed sequentially), block devices (buffered and randomly accessible). Some of these devices are abstractions of physical hardware that actually exist, while others are the functionality provided by the kernel itself (independent of specific physical hardware, also known as "virtual devices"). Each device has a corresponding file (node) in the/dev directory.common

Therefore, under Linux, it is not necessary to build RAMDisk, the direct use of/dev/shm/can achieve a good optimization effect.One of the/dev/shm/needs to be aware of is the capacity issue, which, under Linux, defaults to half the size of memory and can be seen using
