Full Discussion: Getting machine info in C
Top Forums UNIX for Advanced & Expert Users Getting machine info in C Post 302521637 by Corona688 on Thursday 12th of May 2011 01:19:29 AM

In Linux, getting CPU info is easy:
Code:
int fd=open("/proc/cpuinfo", O_RDONLY);
read(...);

As for "primary hard drive" -- what does that even mean now that drives don't come in master/slave pairs? But you can explore quite a lot of Linux device information under /sys/.

Code:
for DEV in /sys/block/*
do
        [ -e "${DEV}/device/model" ] &&
                echo ${DEV}:`cat ${DEV}/device/model`
done

for DEV in /sys/class/net/eth* /sys/class/net/wlan*
do
        [ -d "$DEV" ] || continue
        echo ${DEV}: `cat ${DEV}/address`
done

Code:
/sys/block/sda:TOSHIBA MK3252GS
/sys/block/sdb:Multi-Card
/sys/block/sr0:CDDVDW TS-L633L
/sys/class/net/eth0: 00:23:8b:62:11:cf
/sys/class/net/eth1: 00:21:00:a5:99:05

ip-token

IP-TOKEN(8)							       Linux							       IP-TOKEN(8)

NAME

       ip-token - tokenized interface identifier support

SYNOPSIS

       ip token { COMMAND | help }

       ip token set TOKEN dev DEV

       ip token del dev DEV

       ip token get [ dev DEV ]

       ip token [ list ]

DESCRIPTION

       IPv6 tokenized interface identifier support is used for assigning well-known host-part addresses to nodes whilst still obtaining a global
       network prefix from Router advertisements. The primary target for tokenized identifiers are server platforms where addresses are usually
       manually configured, rather than using DHCPv6 or SLAAC. By using tokenized identifiers, hosts can still determine their network prefix by
       use of SLAAC, but more readily be automatically renumbered should their network prefix change [1]. Tokenized IPv6 Identifiers are described
       in the draft [1]: <draft-chown-6man-tokenised-ipv6-identifiers-02>.

   ip token set - set an interface token
       set the interface token to the kernel.

       TOKEN  the interface identifier token address.

       dev DEV
	      the networking interface.

   ip token del - delete an interface token
       delete the interface token from the kernel.

       dev DEV
	      the networking interface.

   ip token get - get the interface token from the kernel
       show a tokenized interface identifier of a particular networking device.  Arguments: coincide with the arguments of ip token set but the
       TOKEN must be left out.

   ip token list - list all interface tokens
       list all tokenized interface identifiers for the networking interfaces from the kernel.
