电导 vs 电流图表绘制在 matlab 中使用 hspice 仿真工具箱

实现目标 1、用fork创建进程。 2、用共享内存方式实现缓冲区。 3、有2

该程序主要是linux环境下用C语言完成对SQLite数据库的访问和操作,代码简单易懂，适合初学者！

实现了linuxwathLinux 自带了一个 watchdog 的实现，用于监视系统的运行，包括一个内核 watchdog module 和一个用户空间的 watchdog 程序。内核 watchdog 模块通过 /dev/watchdog 这个字符设备与用户空间通信。用户空间程序一旦打开 /dev/watchdog 设备（俗称“开门放狗”），就会导致在内核中启动一个1分钟的定时器（系统默认时间），此后，用户空间程序需要保证在1分钟之内向这个设备写入数据（俗称“定期喂狗”），每次写操作会导致重新设定定时器。如果用户空间程序在1分钟之内没有写操作，定时器到期会导致一次系统 reboot 操作（“狗咬人了”呵呵）。通过这种机制，我们可以保证系统核心进程大部分时间都处于运行状态，即使特定情形下进程崩溃，因无法正常定时“喂狗”，Linux系统在看门狗作用下重新启动（reboot），核心进程又运行起来了. 这个程序就是那个用户空间的程序。

linux下操作串口的应用程序，可以配置波特率，停止位，校验位等，实现字符模式下对串口的操作，通信等。

资源描述非常适合C/C++初学者想做个小项目的要求

模仿windows系统中读取ini文件的格式，读取配置文件信息。可以根据段名和键名获取对于的value值。c++完成，使用了stl::map容器。

参考协议RFC2104，用 c 语言编写，代码简单易懂
