.SH DESCRIPTION
.sp
.LP
These functions return \fBlibdevinfo\fR lnode information.
.sp
.LP
The \fBdi_lnode_name()\fR function returns a pointer to the name associated
with \fIlnode\fR.
.sp
.LP
The \fBdi_lnode_devinfo()\fR function returns a handle to the device node
associated with \fIlnode\fR.
.sp
.LP
The \fBdi_lnode_devt()\fR function sets the \fBdev_t\fR pointed to by the
\fIdevt\fR parameter to the \fBdev_t\fR associated with \fIlnode\fR.
.SH RETURN VALUES
.sp
.LP
The \fBdi_lnode_name()\fR function returns a pointer to the name associated
with \fIlnode\fR.
.sp
.LP
The \fBdi_lnode_devinfo()\fR function returns a handle to the device node
associated with \fIlnode\fR.
.sp
.LP
The \fBdi_lnode_devt()\fR function returns 0 if the requested attribute exists
in \fIlnode\fR and was returned. It returns \(mi1 if the requested attribute
does not exist and sets \fBerrno\fR to indicate the error.
.SH ERRORS
.sp
.LP
The \fBdi_lnode_devt()\fR function will fail if:
