IOCTL_HAL_GETBUSDATA

  • Article

This IOCTL can be customized by the OEM to meet the needs of their platform. This is a sub-code of IOCTL_HAL_DDK_CALL, which is used by the implementation of Ceddk.dll as ported by the OEM to their platform. This IOCTL is only called in the context of Ceddk.dll. The OEMIoControl function calls this IOCTL.

Parameters

  • dwIoControlCode
    [in] Set to IOCTL_HAL_GETBUSDATA.
  • lpInBuf
    [in] Set to NULL.
  • nInBufSize
    [in] Set to 0.
  • lpOutBuf
    [out] Pointer to a BUSDATA_PARMS structure that describes the bus data being read.
  • nOutBufSize
    [in] Set to sizeof(BUSDATA_PARMS).
  • lpBytesReturned
    [in] Set to NULL.

Return Values

TRUE indicates success. FALSE indicates failure.

Remarks

This sub-code reads data from bus address specified in the BUSDATA_PARMS parameter into a buffer, also specified in the structure.

The lpBytesReturned parameter is not accessed. The ReturnCode member of BUSDATA_PARMS provides status if the KernelIoControl call succeeds.

Requirements

OS Versions: Windows CE .NET 4.0 and later.
Header: Platform OAL.
