.In sys/mount.h

|
.In ufs/ufs/ufsmount.h

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
library and the functions it provides are used for implementing
|
|
utilities which need to access a UFS file system at a low level from
|
|
userland.
|
|
Facilities provided are used to implement utilities such as
|
|
.Xr newfs 8
|
|
and
|
|
.Xr dumpfs 8 .
|
|
The
|
|
.Nm
|
|
library is designed to be simple, and to provide functions that are
|
|
traditionally useful to have.
|
|
.Pp
|
|
A disk is represented as the type
|
|
.Vt "struct uufsd"
|
|
as defined in
|
|
.In libufs.h .
|
|
The structure is filled out, operations are performed, and the disk
|
|
is closed.
|
|
.Sh ERRORS
|
|
Functions provided by
|
|
.Nm
|
|
return \-1 in every functional error situation.
|
|
They also set the
|
|
.Va d_error
|
|
field of
|
|
.Vt "struct uufsd"
|
|
to a string describing the error.
