help in searching the path of some basic HW values

[ramziur]

heya!

I would like know in which file is the machine name, os type and processor architecture stored in??
I wouldl like to know the path to those files where the value for os is i386 and machine i686 is something like this..... in which file the systemuser and the number of users of that system is stored

/usr/src/redhat/RPMS/ ... in these files i686 and i 386 is stored as directories and not as values....
but i want them as values in the file

hostname:
cat /etc/sysconfig/network
hostname
uname -n

os type:
Hmm, linux?
The release number is here
cat /etc/redhat-release

processor architecture
cat /proc/cpuinfo
dmidecode

i386 or i686
Can be judged from the processor architecture

systemuser(s)
cat /etc/passwd
wc -l /etc/passwd
It is possible to store users in other places like ldap

Thank you ....
but the problem is system calls are not supported... the command cant be used....so im keen on knowing the pathnames of the files that store all these values....

/proc/sys/kernel/ostypes ... this gives me the kernel name....
simillary i wanted to know file pathanmes that gives me the machine architecture and os type... whose values are i386 and i686..... which we get using the uname -i and uname -m

/etc/passwd this gives a list of users ..... but I need the file that contains the current user name and his UID userNumber in a file??

please help...

Hello!
In the previous post i meant to ask OS name.... where is that name stored in which file??


on executing this program im getting segmentation fault....
I dont whats wrong in declaration of variables.....

#include<stdio.h>
#include<stdlib.h>
#include<unistd.h>
#include<string.h>

int main()
{

FILE * buf, *out;
char var[500];
char os[100];
system("uname -o > out");
buf=fopen("out","r");
while(fgets(var,sizeof(var),buf));
{
strcpy(os,var);
printf("os is: %s",os);
}
rewind(out);
fclose(buf);
return 0;

}

Are you sure buf has a value when you use it? Always test pointers for value before use...
