SpBlockPtr spBlkPtr ; address of 56-byte Slot Parameter Block
structure
InsertSRTRec adds an sResource data structure to the Slot Resource
Table.
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
Æ spParamData long 4 24 Flags
Æ spRefNum short 2 38 Slot Resource Table RefNum
Æ spSlot char 1 49 Slot number
Æ spID char 1 50 ID of the sResource
Æ spExtDev char 1 51 ID of external device
noErr (0) No error
memFullErr (-108) Not enough room in heap..
smUnExBusErr (-308) An unexpected bus error occurred.
Resource Table. You can use the function to restore an sResource data
structure that was deleted from the Slot Resource Table with the
SDeleteSRTRec function. For example, if the user makes a selection in
the Monitors control panel that requires your video card to switch to a new
sResource data structure that was deleted by the PrimaryInit code, you can
You specify an sResource data structure with the spSlot, spID, and
spExtDev fields. You must set the spsPointer to all zeros. Set the
spParamData field to 1 to disable the restored sResource data structure or
to 0 to enable it.
If you place a valid device-driver reference number in the spRefNum
driver's DCE data structure (that is, in the DCE that has that
device-driver reference number in the dCtlRefNum field). The dCtlDevBase
field contains the base address of the memory buffer for data provided by
the sResource data structure that is used by that particular device driver.
flag) of the sRsrc_Flags field of the sResource data structure and the
MinorBaseOS or MajorBaseOS field of the sResource data structure.

Macintosh Family, second edition.
This routine can return the non-fatal error:
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.
smSlotOOBErr (-337) The given slot was out of bounds (or does not exist).
smNoMoresRsrcs (-344) No more sResources.
smBadsPtrErr (-346) A bad sPointer was presented to sCalcsPointer.
smByteLanesErr (-347) NumByteLanes was determined to be zero.
