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
