Handle to \fBprom\fR returned by \fBdi_prom_init()\fR.
.RE

.SH DESCRIPTION
.sp
.LP
For device nodes whose \fBnodeid\fR value is \fBDI_PROM_NODEID\fR (see
\fBdi_nodeid\fR(3DEVINFO)), additional properties can be retrieved from the
\fBPROM\fR. The \fBdi_prom_init()\fR function returns a handle that is used to
retrieve such properties. This handle is passed to
\fBdi_prom_prop_lookup_bytes\fR(3DEVINFO) and
\fBdi_prom_prop_next\fR(3DEVINFO).
.sp
.LP
The \fBdi_prom_fini()\fR function destroys the handle  and all handles to the
\fBPROM\fR device information obtained from that handle.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fBdi_prom_init()\fR returns a handle. Otherwise,
\fBDI_PROM_HANDLE_NIL\fR is returned and \fBerrno\fR is set to indicate the
error.
.SH ERRORS
.sp
.LP
The \fBdi_prom_init()\fR sets \fBerrno\fR function to any error code that can
also be set by \fBopenprom\fR(4D) or \fBmalloc\fR(3C).
