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
