IOCTL_CDROM_READ_SG (Compact 2013)
3/26/2014
This I/O control message reads scatter buffers from the CD-ROM and stores the information in the CDROM_READ structure. Send this message with DeviceIoControl.
Syntax
BOOL DeviceIoControl(
HANDLE hDevice, // handle to device
DWORD dwIoControlCode, // use IOCTL_CDROM_READ_SG
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
OVERLAPPED lpOverlapped // pointer to OVERLAPPED structure
);
Parameters
- hDevice
[in] Handle to the device.
- dwIoControlCode
[in] Control code for the operation. Use IOCTL_CDROM_READ_SG for this operation.
- lpInBuffer
[in] Set to the address of an allocated SGX_BUF structure.
- nInBufferSize
[in] Set to sizeof(SGX_BUF).
- lpOutBuffer
[in][out] On input, set to the address of an allocated CDROM_READ structure. This is the memory needed for the structure and info storage. On output, a filled CDROM_READ structure.
- nOutBufferSize
[in] Set to sizeof(CDROM_READ).
- lpBytesReturned
[in][out] On input, address of a DWORD that receives the size in bytes of the data returned. On output, set to the number of bytes written to the supplied buffer.
- lpOverlapped
[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.
