NAME
statvfs.h, statvfs - VFS File System information structure
SYNOPSIS

#include <sys/statvfs.h>
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: ST_RDONLY

read-only file system

ST_NOSUID

does not support setuid()/setgid() semantics
