programmatic disk free information

vidi · 06-08-2004, 07:22 AM

Hello everybody,

I'm writing an application that has to run on SuSE and on Montavista. I need to see the amount of disk space available. So far the only option I found was to do a 'df' and then parse the result.

Do you know any other solution to this? I would prefer to do it programmatic way since I think it would be faster and safer (something similar to accessing /proc/meminfo for information about memory usage).

Thanks,
vidi

Hi,

These functions are what you are looking for

Code:

man getmntent

man getfsent

These functions will give me the partition list. They are useful BUT what I need is for each mounted partition to get its size and the available/used space.

Basically what I need is exactly what the command 'df' does but I have to do it in my program. I wouldn't use df as I want to have as little dependencies as possible.
