View the official Win32 API referenceNo description available.
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.
None.
None.
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.
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.
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.
Retrieves information about the types of media supported by a device.
To perform this operation, call the DeviceIoControl function with the following parameters.
BOOL DeviceIoControl(
(HANDLE) hDevice, // handle to device
IOCTL_STORAGE_GET_MEDIA_TYPES_EX, // dwIoControlCode
NULL, // lpInBuffer
0, // nInBufferSize
(LPVOID) lpOutBuffer, // output buffer
(DWORD) nOutBufferSize, // size of output buffer
(LPDWORD) lpBytesReturned, // number of bytes returned
(LPOVERLAPPED) lpOverlapped // OVERLAPPED structure
);
Irp->IoStatus.Status is set to STATUS_SUCCESS if the request is successful.
Otherwise, Status to the appropriate error condition as a NTSTATUS code.
