NAME
sg_get_fs_stats - get filesystem statistics
SYNOPSIS
#include <statgrab.h>
sg_fs_stats *sg_get_fs_stats(int *entries);
DESCRIPTION
The sg_get_fs_stats takes a pointer to an int, entries, which is filled
with the number of mounted file systems the machine has. The return
value is a pointer to the first member of an array of sg_fs_stats
structures; the number of entries in the array is returned in entries.
The function returns statistics about mounted filesystems, including
free space and inode usage.
RETURN VALUES
sg_get_fs_stats returns a pointer to a structure of type sg_fs_stats.

device_name
The name known to the operating system. (eg. on linux it might
be hda)
fs_type
The type of the filesystem.
mnt_point
The mount point of the file system.
size The size, in bytes, of the file system.
used The amount of space, in bytes, used on the filesystem.
avail The amount of space, in bytes, available on the filesystem.
total_inodes
The total number of inodes in the filesystem.
used_inodes
The number of used inodes in the filesystem.
free_inodes
The number of free inodes in the filesystem.
avail_inodes
The number of free inodes available to non-privileged processes.
io_size
A suggested optimal block size for IO operations -- if you’re
reading or writing lots of data, do it in chunks of this size.
block_size
How big blocks actually are on the underlying filesystem
(typically for purposes of stats reporting).
total_blocks
The total number of blocks in the filesystem.
free_blocks
The number of free blocks in the filesystem.
used_blocks
The number of used blocks in the filesystem.
avail_blocks
The number of free blocks available to non-privileged processes.
