The actual scenario is: already have a relatively complex program written in C # (non-WEB programs, implementation of some algorithms), now there is a PHP website, I need to embed this C # application in the PHP Web page to use. Search a lot of

Compiling framework of Linux character Device Driver   I. Concepts of Linux device driver A system call is an interface between the operating system kernel and applications, and a device driver is an interface between the operating system kernel and

A Linux Device Driver ConceptA system call is an interface between the operating system kernel and applications, and a device driver is an interface between the operating system kernel and machine hardware. The device driver shields the application

In an embedded system, the operating system uses various drivers to control hardware. The device driver is the interface between the operating system kernel and the hardware device. It shields the application from hardware details. In this way, the

Linux Kernel compilation and InstallationGuideThe Linux kernel is a POSIX-compliant Unix-like operating system written in C language. the kernel is the most basic part of the operating system and provides a mechanism for many applications to access

Environment:CentOS-6.9Pre-compilation Preparation work:(1) Prepare the development environment.~]# Yum Groupinstall Server Platform Development development Tools #安装所需要的软件包组(2) Get information about hardware devices on the target host~]#

The composition of the 1.Linuxconsists of kernel and corresponding function module, kernel/boot/vmlinuz-"kernel version number" file, module file in/lib/modules/version number/directory (for. ko files)In the/proc/sys/directory can modify the file to

*********************************************************************** * Many of the following steps are very elementary commands or explanations, because I am a novice to Linux, * In the process of compiling a lot of detours, spent a lot of time

Here are five steps to compile the Linux makefile:compile total of five parts1. Setting up the compilation environment set compile environment2. Get the source file to compile and convert the source file to the destination file (source and

The standard library defines four IO objects, namely CIN for standard input, cout for standard output, error output Cerr, general information output clog.Each C + + expression produces a result, for the operator is the output input operator, and the

Porting the Linux kernel is to allow the Linux system to run on its own hardware platform and work properly. One of the most important is the driver's migration, only the driver can drive the hardware device, the upper layer of the application to

First, the concept of a briefThere are two ways to load drivers under Linux: Static loading and dynamic loading.Static loading is the driver directly compiled into the kernel, the system can be called directly after booting. The disadvantage of

Ext.: http://hi.baidu.com/firstm25/item/8fe022155e1fa78988a9568fSummary: The device driver is the interface between the operating system kernel and the machine hardware. The device driver masks the hardware details for the application. Then how the

Normally we need to invoke the functions and variables in the executable program directly from the dynamic library, and if the-l option is called, the Linux process will automatically add the functions and variables of the dynamic library to the

Recently in the study of embedded Linux driver development, a general understanding of the basic driver development process, this article is mainly for the character device driver development to do a brief introduction, but also as a small summary
