sg_get_fs_stats(3)

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.
