How to get Hard Disk Info Using C program

[helpmeforlinux]

Does any body knows how to find hard disk information using c proramg, like Total Size of disk, mounted partitions, unmounted partitions, unused size , serial no etc.

procfs is your friend

Surf /proc and see partitions file and ide directory... and read the procfs documentation that comes with the kernel source.

The way you should gather system information is using procfs. It is it's purpose.
In addition, you have two alternatives:

• Execute the sysctl command: This is really dirty.
• Use the sysctl system call: If you carefully read the man page, at the bottom, you can find this:
  

  The object names vary between kernel versions. THIS MAKES THIS SYSTEM CALL WORTHLESS FOR APPLICATIONS. Use the /proc/sys interface instead.

Although it's possible to gather the information that you want by means of other system calls / functions, using procfs is what top, ps and other tools do. (and I'm not sure, but free and df probably do too)
