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

Use the Linux server/dev/shm/to release the disk pressure Browse:646 | Updated: 2013-06-18 18:08 | Tags: disk 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
