IOCTL_STORAGE_GET_MEDIA_TYPES_EX IOCTL (ntddstor.h)
Returns information about the types of media supported by a device. A storage class driver must handle this IOCTL to control devices to be accessed by the removable storage manager (RSM) either as stand-alone devices or as data transfer elements (drives) in a media library or changer device.
Major code
Input buffer
None.
Input buffer length
None.
Output buffer
The driver returns an array of DEVICE_MEDIA_INFO structures, one for each media type supported by the device, embedded in a GET_MEDIA_TYPES structure 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(GET_MEDIA_TYPES) plus additional device-type-specific data, if any.
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 or STATUS_INSUFFICIENT_RESOURCES.
