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.
