SFindDevBase
SpBlockPtr spBlkPtr ; address of 56-byte Slot Parameter Block
structure
SFindDevBase returns a pointer in spResult to the base of a device whose slot number is in spSlot and whose sResource ID is in spID.
spBlkPtr is the address of a 56-byte Slot Parameter Block structure.
The relevant fields are as follows:
Out-In Name Type Size Offset Description
¨ spResult long 4 0 FUNCTION result
Æ spID char 1 50 sResource list ID
Æ spSlot char 1 49 Slot number
noErr (0) No error
smEmptySlot (-300) No card in slot.
smCRCFail (-301) CRC check failed.
smFormatErr (-302) FHeader format is not Apple's
smRevisionErr (-303) The revision of the card's declaration ROM is wrong.
smNoDir (-304) Directory offset is NIL
smNosInfoArray (-306) The SDM could not allocate memory for the sInfo
array.
smResrvErr (-307) A reserved field of the declaration ROM was used.
smUnExBusErr (-308) An unexpected bus error occurred.
smBLFieldBad (-309) A valid ByteLanes field was not found.
smDisposePErr (-312) An error occurred during execution of DisposPointer.
smNoBoardSRsrc (-313) There is no board sResource.
smGetPRErr (-314) Error during execution of sGetPRAMRec.
smNoBoardId (-315) There is no board ID.
smInitStatVErr (-316) The InitStatus_V field was negative after Primary or
Secondary Init.
smInitTblVErr (-317) Error while trying to initialize the sResource Table.
smNoJmpTbl (-318) Slot Manager jump table could not be created smBadBoardId (-319) Board ID was wrong; reinit the PRAM record
Notes: The base address of a device may be in either slot or superslot space but
not in both. Slot or superslot slot spaces are discussed in the book Designing Cards and Drivers for Macintosh II and Macintosh SE.
