This structure contains information that the OALIoCtlHalDdkCall function uses when calling the OAL.

typedef struct {  UINT32 function;  UINT32 rc;  union {    struct {      DEVICE_LOCATION devLoc;      UINT32 offset;      UINT32 length;      VOID *pBuffer;    } busData;    struct {      INTERFACE_TYPE ifcType;      UINT32 busNumber;      UINT32 space;      UINT64 address;    } transAddress;    struct {      INTERFACE_TYPE ifcType;      UINT32 busNumber;    } busPower;  };} OAL_DDK_PARAMS;

  • function
    [in] IOCTL that specifies which function to call. Set to IOCTL_OAL_READBUSDATA, IOCTL_OAL_WRITEBUSDATA, IOCTL_OAL_TRANSBUSADDRESS, IOCTL_OAL_TRANSSYSADDRESS, IOCTL_OAL_BUSPOWEROFF, or IOCTL_OAL_BUSPOWERON.
  • rc
    [out] Return code from the function member.
  • devLoc
    [in] Pointer to a DEVICE_LOCATION structure.
  • offset
    [in] Offset into the buffer.

  • address
    [in] Bus-relative address or the system address.
  • ifcType
