SReadLong
SpBlockPtr spBlkPtr ; address of 56-byte Slot Parameter Block
structure
SReadLong returns a 32-bit value identified by 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 spsPointer Ptr 4 4 Structure pointer Æ spID char 1 50 sResource list ID
Other parameters affected are:
spSize long 4 8 Size of structure
sp sOffsetData long 4 12 Offset/data field
spByteLanes char 1 53 ByteLanes from format block in card ROM
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 trap macro SReadLong finds a data structure in slot card firmware. It returns in spResult a 32-bit value identified by spID from the sResource
list pointed to by spsPointer. This routine can return nonfatal error
re ports, which will 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.
