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.

               long long used_blocks;
               long long avail_blocks;
       } 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.
