操作系统作业: 在UNIX环境下用C语言编写一段程序显示系统信息。这个他代码应该写在哪里啊?

这是我写的代码你拿去参考一下,在UNIX中主要是调用POSIX API,跟Linux中一样:

#include unistd.h

#include stdio.h

#include sys/utsname.h

int main(int argc,char* argv[])

{

  int i;

  struct utsname name;

  printf("Logged User:\t\t%s\n",getlogin());

  printf("User ID:\t\t%lu\n",getuid());

  for(i=0;i15;i++)putchar('-');

  putchar(0xa);

  printf("System Information Here:\n");

  printf("Memory page size:\t%lu\n",getpagesize());

  if(uname(name)!=-1){

    printf("Name of the implementation of the operating system:%s\n",name.sysname);

    printf("Name of this node on the network:%s\n",name.nodename);

    printf("Current release level of this implementation:%s\n",name.release);

    printf("Current version level of this release:%s\n",name.version);

    printf("Name of the hardware type the system is running on:%s\n",name.machine);

    printf("Name of the domain of this node on the network:%s\n",name.__domainname);

  }

  return 0;

}

获取信息其实可以很多,我的这个只是一个小部分。

如果你要获取一些硬件信息,可以打开/proc目录下的一些映射文件,如:要得知CPU的信息,则只要打开/proc/cpuinfo文件,查看该文件即可。

用system,个人感觉很“鸡肋”。

这是我的运行效果截图:

我在Linux中调试就是gdb,在编译时加一个参数“-g”。

即为:gcc -o code code.c -g

code.c是我的代码文件。

UNIX中有个cc编译器,应该跟gcc差不多。

windows下C/C++如何获得当前主机的信息:操作系统版本、系统类型、CUP、网卡、内存和磁盘的利用率?

示例代码如下:

GetsysInfo.h:

#ifndef _H_GETSYSINFO

#define _H_GETSYSINFO

#pragma once

#include afxtempl.h

class GetSysInfo

{

public:

GetSysInfo(void);

~GetSysInfo(void);

public:

/********获取操作系统版本,Service pack版本、系统类型************/

void GetOSVersion(CString strOSVersion,CString strServiceVersion);

BOOL IsWow64();//判断是否为64位操作系统

/***********获取网卡数目和名字***********/

int  GetInterFaceCount();

void GetInterFaceName(CString InterfaceName,int pNum);

/***获取物理内存和虚拟内存大小***/

void GetMemoryInfo(CString dwTotalPhys,CString dwTotalVirtual);

/****获取CPU名称、内核数目、主频*******/

void GetCpuInfo(CString chProcessorName,CString chProcessorType,DWORD dwNum,DWORD dwMaxClockSpeed);

/****获取硬盘信息****/

void GetDiskInfo(DWORD dwNum,CString chDriveInfo[]);

/****获取显卡信息*****/

void GetDisplayCardInfo(DWORD dwNum,CString chCardName[]);

private:

CStringList Interfaces;                   //保存所有网卡的名字

CList  DWORD, DWORD  Bandwidths;   //各网卡的带宽

CList  DWORD, DWORD  TotalTraffics;    //各网卡的总流量

};

#endif
