DESCRIPTION

The <sys/statvfs.h> header defines the statvfs structure, which
includes the following members:

unsigned long f_bsize /* file system block
size */
unsigned long f_frsize /* fundamental file system block
size */
fsblkcnt_t f_blocks /* total number of blocks on file
system in units of f_frsize */
fsblkcnt_t f_bfree /* total number of free blocks */
fsblkcnt_t f_bavail /* number of free blocks available
to non-privileged process */
fsfilcnt_t f_files /* total number of file serial
numbers */
fsfilcnt_t f_ffree /* total number of free file serial
numbers */
fsfilcnt_t f_favail /* number of file serial numbers
available to non-privileged
unsigned long f_fsid /* process file system ID */
unsigned long f_flag /* bit mask of f_flag values */
unsigned long f_namemax /* maximum filename length */


The fsblkcnt_t and fsfilcnt_t types are defined as described in
<sys/types.h>. See types.h(3HEAD).


The following flags for the f_flag member are defined:
