How about executing a command in the console (from your program that is) for that info and then storing it in a string object, then you can do whatever you want with that data.

This is the way to find out the hard disk serial number using C code
/*
* didkinfo.c
* It gets the hard disk information in this case serial no.
* It uses ioctl() system call
*/
#include <linux/types.h>
#include <linux/hdreg.h>
#include <linux/fcntl.h>
int main()
{
int fd,err,i;
/* structure to get disk information and
* returned by HDIO_GET_IDENTITY, as per ANSI ATA2 rev.2f spec
*/
struct hd_driveid hd;
/* open the device */
if( (fd=open("/dev/hda", O_RDONLY ) ) < 0 )
perror("Device Open Error");
/* get required info */
if( (err = ioctl(fd,HDIO_GET_IDENTITY,&hd) ) < 0)
perror("IOCTL err");
else
printf("Serial No = %s\n",hd.serial_no);
return (0);
}
