API for getting free space information in Linux.

srns · 04-26-2005, 02:50 PM

Hello,

Is there an API in Linux that I can use to find the hard disk usage? I would like to know the available free space every once in a while. Right now, I am using df, but it's not efficient.

Thanks..

Krusader 1.6 has a Disk Usage plugin or use Filelight:

take a look at the man pages for:

getmntent()
setmntent()

Let me clarify..

I am storing some data continuously to the disk. Periodically I check the free space on the disk. I use df and some massaging of the data to get the number. But, it's a pain.

Is there a system call which I can use to get this info? getmntent() seems to show only the information in fstab and mtab.

statvfs() and fstatvfs()

#include <sys/statvfs.h>

I went to the source code listing and went thru all available system calls. I already got the info, and implemented it in my code. Works fine!

Check out this site for source code (if you didn't knew):

Thanks anyway..
