.Sh NAME
.Nm statvfs
.Nd file system statistics
.Sh SYNOPSIS
.In sys/types.h
.In sys/statvfs.h
.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.
