28 * SMBIOS Information Routines
29 *
30 * The routines in this file are used to convert from the SMBIOS data format to
31 * a more reasonable and stable set of structures offered as part of our ABI.
32 * These functions take the general form:
33 *
34 * stp = smb_lookup_type(shp, foo);
35 * smb_foo_t foo;
36 *
37 * smb_info_bcopy(stp->smbst_hdr, &foo, sizeof (foo));
38 * bzero(caller's struct);
39 *
40 * copy/convert foo members into caller's struct
41 *
42 * We copy the internal structure on to an automatic variable so as to avoid
43 * checks everywhere for structures that the BIOS has improperly truncated, and
44 * also to automatically handle the case of a structure that has been extended.
45 * When necessary, this code can use smb_gteq() to determine whether the SMBIOS
46 * data is of a particular revision that is supposed to contain a new field.
