dm6467的驱动源码 针对网络层的驱动 简易 的C语言 值得收藏(dm6467 driver source code for easy drive of the network layer of the C language worthy of collection )

描述了exata 5.4 源码的调试方法，以及如何导入studio(Describes the EXATA 5.4 source code debugging method)

一个windows显示驱动的好程序，对学习驱动开发很有好处(a windows driver of the program is to study the development of a very good driver)

通用键盘鼠标模拟(包括USB和PS2) 通过直接调用Kbdclass的回调函数KeyboardClassServiceCallback直接给上层发送键盘驱动。这个方法网上已经公开，参考 Hook KeyboardClassServiceCallback实现键盘 Logger，其他的还有很多，可以到网上去查。 简单说一下没有公开的部分，就是按下和松开的模拟，已经扩展键的模拟。 模拟主要是构造KEYBOARD_INPUT_DATA结构，按下和松开的Flags分别对应KEY_MAKE、KEY_BREAK，然后调用KeyboardClassServiceCallback。(Universal keyboard and mouse simulation (including USB and PS2))

linux系统下3G模块USB串口驱动程序源代码最新版本，附pdf文档档。3G的USB modem都用得着，有了这个就可以在linux下使用了。 (3G module USB serial port driver in the linux system source code version of the attached pdf document file. 3G USB modem need it, with this you can use under linux.)

枚举驱动列表，获取驱动的设备句柄 这是Win7上常用的获取设备句柄的方法。 我在原代码的基础上，添加了SetupDiEnumDeviceInterfaces 来获取驱动的详细信息。(SetupDiEnumDeviceInterfaces SetupDiGetClassDevs SetupDiEnumDeviceInterfaces)

VB、VC混合编程中字符串的传递，源代码，使用VC制作动态库在VC、VB中使用。(VB, VC mixed programming string transmission, the source code, the use of VC production of dynamic libraries in VC, VB use.)

在linux环境下编写一个控制台应用程序，程序中有一个共享的整型变量shared_var，初始值为0；创建一个线程并使其立即与主线程并发执行。新创建的线程与主线程均不断地循环，并输出shared_var 的值。主线程在循环中不断地对shared_var 进行加1操作，即每次循环shared_var 被加1；而新创建的线程则不断地对shared_var 进行减1 操作，即每次循环shared_var 被减1。观察程序运行的结果，并对你看到的现象进行解释。(Written in the linux environment a console application, the program has a shared integer variable shared_var, the initial value of 0 create A thread and make it run concurrently with the main thread immediately. The newly created thread and main thread are constantly circulating, and the output shared_var Value. The main thread in a loop constantly on shared_var are incremented, that is plus 1 for each cycle shared_var and the new line created Process is constantly on the shared_var decremented, that is, each cycle shared_var is decreased by 1. Observe the results of running the program, and you To explain the phenomenon seen.)
