-.Nm openprom
-.Nd OPENPROM interface
-.Sh SYNOPSIS
-.In machine/openpromio.h
-.Sh DESCRIPTION
-The file
-.Pa /dev/openprom
-is an interface to the Macintosh OPENPROM.
-This interface is highly stylized;
-ioctls are used for all operations.
-These ioctls refer to
-.Dq nodes ,
-which are simply
-.Dq magic
-integer values describing data areas.
-Occasionally the number 0 may be used or returned instead,
-as described below.
-.Pp
-The calls that take and/or return a node
-use a pointer to an
-.Li int
-variable for this purpose;
-others use a pointer to a
-.Li struct opiocdesc
-descriptor,
-which contains a node and two counted strings.
-The first string is comprised of the fields
-.Li op_namelen
-(an
-.Li int )
-and
-.Li op_name
-(a
-.Li "char *" ) ,
-giving the name of a field.
-The second string is comprised of the fields
-.Li op_buflen
-and
-.Li op_buf ,
-used analogously.
-These two counted strings work in a
-.Dq value-result
-fashion.
-At entry to the ioctl,
-the counts are expected to reflect the buffer size;
-on return,
-the counts are updated to reflect the buffer contents.
-.Pp
-The following ioctls are supported:
-.Bl -tag -width OPIOCGETOPTNODE
-.It Dv OPIOCGETOPTNODE
-Takes nothing, and fills in the options node number.
-.It Dv OPIOCGETNEXT
-Takes a node number and returns the number of the following node.
-The node following the last node is number 0;
-the node following number 0 is the first node.
-.It Dv OPIOCGETCHILD
-Takes a node number and returns the number of the first
-.Dq child
-of that node.
-This child may have siblings; these can be discovered by using
-.Dv OPIOCGETNEXT .
-.It Dv OPIOCGET
-Fills in the value of the named property for the given node.
-If no such property is associated with that node,
-the value length is set to -1.
-If the named property exists but has no value,
-the value length is set to 0.
-.It Dv OPIOCSET
-Writes the given value under the given name.
-The OPENPROM may refuse this operation;
-in this case
-.Dv EINVAL
-is returned.
-.It Dv OPIOCNEXTPROP
-Finds the property whose name follows the given name
-in OPENPROM internal order.
-The resulting name is returned in the value field.
-If the named property is the last, the
-.Dq next
-name is the empty string.
-As with
-.Dv OPIOCGETNEXT ,
-the next name after the empty string is the first name.
-.El

-.It Bq Er EINVAL
-The given node number
