.SH DESCRIPTION
.sp
.LP
The \fBdi_minor_next()\fR function returns a handle to the next minor node for
the device node \fInode\fR. If \fIminor\fR is \fBDI_MINOR_NIL\fR, a handle to
the first minor node is returned.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, a  handle to the next minor node is returned.
Otherwise, \fBDI_MINOR_NIL\fR is returned and \fIerrno\fR is set to indicate
the error.
.SH ERRORS
