Size of Harddisc

[666cartman]

How can i get the size of an HD on a Linux system ?
I need it for an Benchmark program i am writing.

i need a c-function that can get me the size of the hd,
without using system(), via ftell and fseek i can determine the size of a file, but as soon as i try to use this on eg. dev/hda it all goes wrong,
in my programm the file is opened via low-level i/o,
it works perfectly as long as i open a single file, as soon as i try to open the /dev/hda it all goes wrong

That's because /dev/hda is a device, not a file. I guess you could take a look at df's source code, as it is open source. You could probably find what you need in there. //Daniel
