One can only bzero the initial version that existed in illumos. In * other words, if someone passes an older library handle that doesn't support a * version you cannot assume that their structures have those additional members * in them. Instead, a 'base' version is introduced for such types that have * differences and instead we only bzero out the base version and then handle * the additional members. In general, because all additional members will be * assigned, there's no reason to zero them out unless they are arrays that * won't be entirely filled in. * * Due to history, anything added after the update from version 2.4, in other * words additions from or after '5094 Update libsmbios with recent items' * (4e901881) is currently being used for this. While we don't allow software * compiling against this to get an older form, this was the first major update * and a good starting point for us to enforce this behavior which is useful for * moving forward to making this more public. */ #include #ifdef _KERNEL #include #else #include #include #include #endif /* * A large number of SMBIOS structures contain a set of common strings used to * describe a h/w component's serial number, manufacturer, etc. These fields * helpfully have different names and offsets and sometimes aren't consistent. * To simplify life for our clients, we factor these common things out into * smbios_info_t, which can be retrieved for any structure.
