任务1.熟悉和理解Linux编程环境 4 | ### 1-1 文件拷贝 5 | 编写一个C程序，用read、write等系统调用实现文件拷贝功能。命令形式：copy <源文件名> <目标文件名>。[详细信息](https://github.com/isypang/OsCourseDesign/blob/master/ex1-1/ex1-1.md) 6 | ### 1-2 进程并发 7 | 编写一个C程序，使用图形编程库 (QT/GTK)分窗口显示三个并发进程的运行(一个窗口实时显示当前系统时间，一个窗口循环显示0到9，一个窗口做1到1000的累加求和，刷新周期均为1秒)。 8 | 9 | ## 任务2.掌握添加系统调用的方法 10 | 采用编译内核的方法，添加一个新的系统调用，实现文件拷贝功能。编写一个应用程序，测试新加的系统调用。 11 | 12 | ## 任务3.掌握添加设备驱动程序的方法 13 | 采用模块方法，添加一个新的字符设备驱动程序，实现打开/关闭、读/写等基本操作。编写一个应用程序，测试添加的驱动程序。 14 | 15 | ## 任务4.理解和分析/proc文件 16 | 通过读取proc文件系统，获取系统各种信息，并以比较容易理解的方式显示出来。具体包括：主机名、系统启动时间、系统运行时间、版本号、所有进程信息、CPU类型、CPU的使用率、内存使用率……----参照WINDOWS的任务管理器，实现其中的部分功能。 17 | -------------------------------------------------------------------------------- /build-ex1-Desktop_Qt_5_12_1_GCC_64bit-Debug/.qmake.stash: -------------------------------------------------------------------------------- 1 | QMAKE_CXX.QT_COMPILER_STDCXX = 201402L 2 | QMAKE_CXX.QMAKE_GCC_MAJOR_VERSION = 7 3 | QMAKE_CXX.QMAKE_GCC_MINOR_VERSION = 3 4 | QMAKE_CXX.QMAKE_GCC_PATCH_VERSION = 0 5 | QMAKE_CXX.COMPILER_MACROS = \ 6 | QT_COMPILER_STDCXX \ 7 | QMAKE_GCC_MAJOR_VERSION \ 8 | QMAKE_GCC_MINOR_VERSION \ 9 | QMAKE_GCC_PATCH_VERSION 10 | QMAKE_CXX.INCDIRS = \ 11 | /usr/include/c++/7 \ 12 | /usr/include/x86_64-linux-gnu/c++/7 \ 13 | /usr/include/c++/7/backward \ 14 | /usr/lib/gcc/x86_64-linux-gnu/7/include \ 15 | /usr/local/include \ 16 | /usr/lib/gcc/x86_64-linux-gnu/7/include-fixed \ 17 | /usr/include/x86_64-linux-gnu \ 18 | /usr/include 19 | QMAKE_CXX.LIBDIRS = \ 20 | /usr/lib/gcc/x86_64-linux-gnu/7 \ 21 | /usr/lib/x86_64-linux-gnu \ 22 | /usr/lib \ 23 | /lib/x86_64-linux-gnu \ 24 | /lib 25 | -------------------------------------------------------------------------------- /build-ex1-Desktop_Qt_5_12_1_GCC_64bit-Debug/ex1: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/GuanyunFeng/OsCourseDesign/26d23557c1143aeaa65ef425f556336598e362a6/build-ex1-Desktop_Qt_5_12_1_GCC_64bit-Debug/ex1 -------------------------------------------------------------------------------- /build-ex1-Desktop_Qt_5_12_1_GCC_64bit-Debug/main.o: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/GuanyunFeng/OsCourseDesign/26d23557c1143aeaa65ef425f556336598e362a6/build-ex1-Desktop_Qt_5_12_1_GCC_64bit-Debug/main.o -------------------------------------------------------------------------------- /build-ex1-Desktop_Qt_5_12_1_GCC_64bit-Debug/moc_predefs.h: -------------------------------------------------------------------------------- 1 | #define __SSP_STRONG__ 3 2 | #define __DBL_MIN_EXP__ (-1021) 3 | #define __FLT32X_MAX_EXP__ 1024 4 | #define __cpp_attributes 200809 5 | #define __UINT_LEAST16_MAX__ 0xffff 6 | #define __ATOMIC_ACQUIRE 2 7 | #define __FLT128_MAX_10_EXP__ 4932 8 | #define __FLT_MIN__ 1.17549435082228750796873653722224568e-38F 9 | #define __GCC_IEC_559_COMPLEX 2 10 | #define __UINT_LEAST8_TYPE__ unsigned char 11 | #define __SIZEOF_FLOAT80__ 16 12 | #define __INTMAX_C(c) c ##

由于任务要求调用形式：copy <源文件名> <目标文件名>，需要获取命令行参数，main函数需要写成带命令行参数的形式： 11 | ```c 12 | int main(int argc, char *argv[]){} 13 | ``` 14 |
若符合任务要求的调用形式：copy <源文件名> <目标文件名>， 则main函数会接受到3个参数。第一个参数是隐藏的，即当前程序路径，不需要显示输入。第二个参数是源文件路径。第三个是目的文件路径。判断文件是否可以打开后，报错或开始文件拷贝。 15 | ```c 16 | if(argc == 3){ //命令行传入源文件和目的文件地址 17 | if((src = fopen(argv[1], "rb")) == NULL){ 18 | printf("src error: 源文件无法打开或不存在\n"); 19 | return 0; 20 | } 21 | if((des = fopen(argv[2], "wb")) == NULL){ 22 | printf("des error: 不合法的目的文件路径\n"); 23 | return 0; 24 | } 25 | } 26 | ``` 27 |
若仅输入程序名，则main函数只接收到一个参数，即当前程序路径。这个参数忽略即可，在这个任务中没什么用。但要知道有这个参数，因此其判断条件是argc==1。由于没有获取源文件和目的文件路径，需要在程序内输入其路径。 28 | ```c 29 | else if(argc == 1){ //命令行为传入参数，程序内输入 30 | char tmp[128]; 31 | scanf("%s", tmp); 32 | if((src = fopen(tmp, "rb")) == NULL){ 33 | printf("src error: 源文件无法打开或不存在\n"); 34 | return 0; 35 | } 36 | scanf("%s", tmp); 37 | if((des = fopen(tmp, "wb")) == NULL){ 38 | printf("des error: 不合法的目的文件路径\n"); 39 | return 0; 40 | } 41 | } 42 | ``` 43 | 44 | -------------------------------------------------------------------------------- /ex1-2/ex1.pro: -------------------------------------------------------------------------------- 1 | #------------------------------------------------- 2 | # 3 | # Project created by QtCreator 2019-02-09T20:33:15 4 | # 5 | #------------------------------------------------- 6 | 7 | QT += core gui widgets 8 | 9 | TARGET = ex1 10 | TEMPLATE = app 11 | 12 | # The following define makes your compiler emit warnings if you use 13 | # any feature of Qt which has been marked as deprecated (the exact warnings 14 | # depend on your compiler).
