.SH DESCRIPTION
.LP
The \fBfstyp_get_attr()\fR function returns a name-value pair list of various
attributes for an identified file system. This function can be called only
after a successful call to \fBfstyp_ident()\fR.
.sp
.LP
Each file system has its own set of attributes. The following attributes are
generic and are returned when appropriate for a particular file system type:
.sp
.ne 2
.na
\fB\fBgen_clean (DATA_TYPE_BOOLEAN_VALUE)\fR\fR
.ad
.sp .6
.RS 4n
Attribute for which \fBtrue\fR and \fBfalse\fR values are allowed. A
\fBfalse\fR value is returned if the file system is damaged or if the file
system is not cleanly unmounted. In the latter case, \fBfsck\fR(1M) is required
before the file system can be mounted.
.RE

.sp
.ne 2
.na
\fB\fBgen_guid (DATA_TYPE_STRING)\fR\fR
.ad
.sp .6
.RS 4n
Globally unique string identifier used to establish the identity of the file
system.
.RE

.sp
.ne 2
.na
\fB\fBgen_version (DATA_TYPE_STRING)\fR\fR
.ad
.sp .6
.RS 4n
String that specifies the file system version.
.RE

.sp
.ne 2
.na
\fB\fBgen_volume_label (DATA_TYPE_STRING)\fR\fR
.ad
.sp .6
.RS 4n
Human-readable volume label string used to describe and/or identify the file
system.
.sp
Attribute names associated with specific file systems should not start with
\fBgen_\fR.
.RE

.SH RETURN VALUES
.LP
The \fBfstyp_get_attr()\fR function returns \fB0\fR on success and an error
value on failure. See \fBfstyp_strerror\fR(3FSTYP).
