.Sh DESCRIPTION
|
|
The
|
|
.Aq Pa sys/statvfs.h
|
|
header defines the structures and functions that
|
|
return information about a mounted file system.
|
|
The
|
|
.Nm statvfs
|
|
structure is defined as follows:
|
|
.Bd -literal
|
|
|
|
struct statvfs {
|
|
unsigned long f_bsize; /* system block size */
|
|
unsigned long f_frsize; /* system fragment size */
|
|
|
|
fsblkcnt_t f_blocks; /* number of blocks in file system */
|
|
fsblkcnt_t f_bfree; /* free blocks avail in file system */
|
|
fsblkcnt_t f_bavail; /* free blocks avail to non-root */
|
|
|
|
fsfilcnt_t f_files; /* total file nodes in file system */
|
|
fsfilcnt_t f_ffree; /* free file nodes in file system */
|
|
fsfilcnt_t f_favail; /* free file nodes avail to non-root */
|
|
|
|
unsigned long f_fsid; /* File system ID */
|
|
|
|
unsigned long f_flag; /* flags */
|
|
|
|
unsigned long f_namemax;/* maximum filename length */
|
|
};
|
|
.Ed
|
|
.Pp
|
|
The
|
|
.Fa f_flag
|
|
argument can have the following bits set:
|
|
.Bl -tag -width ST_SYNCHRONOUS
|
|
.It Dv ST_RDONLY
|
|
The filesystem is mounted read-only;
|
|
Even the super-user may not write on it.
|
|
.It Dv ST_NOSUID
|
|
Setuid and setgid bits on files are not honored when they are executed.
|
|
.It Dv ST_NOTRUNC
