SNextSRsrc
SNextSRsrc Determine the set of all a slot card's or NuBus's sResources SpBlockPtr spBlkPtr ; address of 56-byte Slot Parameter Block
structure
SNextSRsrc can be used to determine the set of all sResources in a given slot card or NuBus configuration.
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
¨ spsPointer Ptr 4 4 Structure pointer ¨ spIOReserved short 2 36 Reserved field of Slot Resource Table
¨ spRefNum short 2 38 Slot Resource Table reference number
¨ spCategory short 2 40 sResource type: Category
¨ spCType short 2 42 sResource type: Type
¨ spDrvrSW short 2 44 sResource type: Driver software identifier
¨ spDrvrHW short 2 46 sResource type: Driver hardware identifier
´ spSlot char 1 49 Slot number
´ spID char 1 50 sResource list ID
´ spExtDev char 1 51 External device identifier
¨ spHwDev char 1 52 Hardware device identifier
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: Starting from a given slot number, spSlot, sResource list identification
number, spID, and external device identifier, spExtDev, the trap macro
SNextSRsrc returns the slot number, sResource list identification number, sResource type (category, cType, software, and hardware), driver
reference number (spRefNum), and Slot Resource Table ioReserved field
(spIOReserved) for the next sResource. If there are no more sResources,
SNextSRsrc returns a nonfatal error status, which can be one of the following:
smBadRefId (-330) Reference ID was not found in the given sResource
list.
smBadsList (-331) The IDs in the sResource list are not in ascending
order.
smReservedErr (-332) A reserved field was not zero.
smCodeRevErr (-333) Wrong revision of the code to be executed by sExec.
smCPUErr (-334) The CPU field of the code was wrong.
smsPointerNil (-335) LPointer is nil From sOffsetData. If this error occurs;
check sInfo rec for more information.
smNilsBlockErr (-336) The physical block size (of an sBlock) was zero.
smSlotOOBErr (-337) The given slot was out of bounds (or does not exist).
smSelOOBErr (-338) Selector out of bounds error
smNewPErr (-339) An error occurred during execution of NewPointer.
smCkStatusErr (-341) Status of slot is bad (InitStatus_A,V).
smGetDrvrNamErr (-342) An error occurred during execution of
sGetDrvrName.
smNoMoresRsrcs (-344) No more sResources.
smsGetDrvrErr (-345) An error occurred during execution of sGetDrvr.
smBadsPtrErr (-346) A bad sPointer was presented to sCalcsPointer.
smByteLanesErr (-347) NumByteLanes was determined to be zero.
smSRTOvrFlErr (-350) Slot Resource Table overflow.
smRecNotFnd (-351) Record not found in the Slot Resource Table.
