30  * SMBIOS Information Routines
31  *
32  * The routines in this file are used to convert from the SMBIOS data format to
33  * a more reasonable and stable set of structures offered as part of our ABI.
34  * These functions take the general form:
35  *
36  *	stp = smb_lookup_type(shp, foo);
37  *	smb_foo_t foo;
38  *
39  *	smb_info_bcopy(stp->smbst_hdr, &foo, sizeof (foo));
40  *      bzero(caller's struct);
41  *
42  *	copy/convert foo members into caller's struct
43  *
44  * We copy the internal structure on to an automatic variable so as to avoid
45  * checks everywhere for structures that the BIOS has improperly truncated, and
46  * also to automatically handle the case of a structure that has been extended.
47  * When necessary, this code can use smb_gteq() to determine whether the SMBIOS
48  * data is of a particular revision that is supposed to contain a new field.
49  *
50  * Note, when trying to bzero the caller's struct you have to be careful about
51  * versions. One can only bzero the initial version that existed in illumos. In
52  * other words, if someone passes an older library handle that doesn't support a
53  * version you cannot assume that their structures have those additional members
54  * in them. Instead, a 'base' version is introduced for such types that have
55  * differences and instead we only bzero out the base version and then handle
56  * the additional members. In general, because all additional members will be
57  * assigned, there's no reason to zero them out unless they are arrays that
58  * won't be entirely filled in.
59  *
60  * Due to history, anything added after the update from version 2.4, in other
61  * words additions from or after '5094 Update libsmbios with recent items'
62  * (4e901881) is currently being used for this. While we don't allow software
63  * compiling against this to get an older form, this was the first major update
64  * and a good starting point for us to enforce this behavior which is useful for
65  * moving forward to making this more public.
