IOCTL_TAPE_PREPARE IOCTL (ntddtape.h)
Loads or unloads the tape, resets tape tension, locks or unlocks the ejection mechanism, or formats the tape.
Major code
Input buffer
The buffer at Irp->AssociatedIrp.SystemBuffer contains a TAPE_PREPARE structure that indicates the type of operation.
If the Immediate member is TRUE, the operation should be asynchronous.
Input buffer length
Parameters.DeviceIoControl.InputBufferLength in the I/O stack location indicates the size, in bytes, of the parameter buffer, which must be >= sizeof(TAPE_PREPARE).
Output buffer
None.
Output buffer length
None.
Status block
The Information field is set to the number of bytes transferred. The Status field is set to STATUS_SUCCESS, or possibly to STATUS_NO_SUCH_DEVICE, STATUS_IO_TIMEOUT, STATUS_IO_DEVICE_ERROR, STATUS_INSUFFICIENT_RESOURCES, STATUS_DEVICE_NOT_CONNECTED, STATUS_MEDIA_WRITE_PROTECTED, STATUS_NO_MEDIA_IN_DEVICE, or STATUS_VERIFY_REQUIRED.
