IOCTL_TAPE_GET_DRIVE_PARAMS IOCTL (ntddtape.h)
Returns information about the tape drive's capabilities, such as its default block size, maximum and minimum block sizes, maximum partition count, whether the drive has EEC, compression, data padding, and report-setmark capabilities, that is, which configurable features the drive supports, including the EOT warning zone size.
Major code
Input buffer
None.
Input buffer length
None.
Output buffer
The driver returns the TAPE_GET_DRIVE_PARAMETERS data in the buffer at Irp->AssociatedIrp.SystemBuffer.
Output buffer length
Parameters.DeviceIoControl.OutputBufferLength in the I/O stack location indicates the size, in bytes, of the parameter buffer, which must be >= sizeof(TAPE_GET_DRIVE_PARAMETERS).
Status block
The Information field is set to the number of bytes returned. The Status field is set to STATUS_SUCCESS, or possibly to STATUS_INFO_LENGTH_MISMATCH, STATUS_IO_DEVICE_ERROR, STATUS_DEVICE_DATA_ERROR, STATUS_NO_SUCH_DEVICE, STATUS_IO_TIMEOUT, or STATUS_DEVICE_NOT_READY.
