How to get device name with device id?

[ashish mahamuni <ashitpro yahoo co in>]

Hi all,

I want to open a device(/dev/sda1, /dev/hda2 etc) in which my file exists.
I've used 'stat' system call to get the device id.

But now I want the device name from this id(st_dev).
How to get that one?
Or 
Do you have any other method to know the device name where my file resides?

Thanks
