IOCTL_OAL_WRITEBUSDATA (Compact 2013)
10/16/2014
This I/O control message 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. It can be customized by OEMs to meet the needs of their platforms. Send this message with OEMIoControl.
Syntax
BOOL OEMIoControl(
DWORD dwIoControlCode, // use IOCTL_OAL_WRITEBUSDATA
LPVOID lpInBuffer, // pointer to input buffer
DWORD nInBufferSize, // input buffer size
LPVOID lpOutBuffer, // pointer to output buffer
DWORD nOutBufferSize, // output buffer size
LPDWORD lpBytesReturned // number of bytes returned
);
Parameters
- dwIoControlCode
[in] Control code for the operation. Use IOCTL_OAL_WRITEBUSDATA for this operation.
- lpInBuffer
[in] Pointer to an OAL_DDK_PARAMS structure that describes the bus data being written.
- nInBufferSize
[in] Set to sizeof(OAL_DDK_PARAMS).
- lpOutBuffer
[in] Set to NULL.
- nOutBufferSize
[in] Set to zero.
- lpBytesReturned
[in] Set to NULL.
Return Values
Returns TRUE if successful; otherwise, returns FALSE.
Remarks
To get extended error information, call GetLastError. GetLastError may return other standard error messages as appropriate.
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.
