IOCTL_OAL_WRITEBUSDATA (Windows Embedded CE 6.0)
1/5/2010
This IOCTL can be customized by OEMs to meet the needs of their platforms.
This IOCTL is a subcode of IOCTL_HAL_DDK_CALL, which is used by the implementation of Ceddk.dll as ported by the OEM to their platform. It is only called in the context of Ceddk.dll.
The OEMIoControl function calls this IOCTL.
Parameters
- dwIoControlCode
[in] Set to IOCTL_OAL_WRITEBUSDATA.
- lpInBuf
[in] Pointer to a OAL_DDK_PARAMS structure describing the bus data being written.
- nInBufSize
[in] Set to sizeof(OAL_DDK_PARAMS).
- lpOutBuf
[in] Set to NULL.
- nOutBufSize
[in] Set to 0.
- lpBytesReturned
[in] Set to NULL.
Return Values
TRUE indicates success.
FALSE indicates failure.
Remarks
This subcode writes data from the buffer specified in the OAL_DDK_PARAMS structure to a specific bus address, which is also specified in the structure. The lpBytesReturned parameter is not accessed. If the KernelIoControl call succeeds, the rc member of OAL_DDK_PARAMS provides status.
