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