# KySdkDisk(3)

Class for generating D-Bus signals for disk information

KySdkDisk.3

## NAME

KySdkDisk - Class for generating D-Bus signals for disk information

## SYNOPSIS

```
#include <kysdkdbus.h>
```

## DESCRIPTION

The **KySdkDisk** class is mainly used to generate D-Bus signals for disk list, number of sectors, bytes per sector, capacity, model, serial number, number of sub-partitions, type, and firmware version information.

This class inherits from **QObject**.

## PUBLIC SLOTS

**QStringList getDiskList () const**

Get the list of all disks.

**Return value:**

- **QStringList**

  List of disks, each string represents the absolute path of a disk

**unsigned int getDiskSectorSize (const QString diskname) const**

Get the number of bytes per sector of the disk.

**Parameters:**

- **diskname**

  Specify the disk name, should be an absolute path such as /dev/sda

**Return value:**

- **unsigned int**

  Number of bytes per sector

**double getDiskTotalSizeMiB (const QString diskname) const**

Get the disk capacity.

**Parameters:**

- **diskname**

  Specify the disk name, should be an absolute path such as /dev/sda

**Return value:**

- **double**

  Disk capacity in MiB

**QString getDiskModel (const QString diskname) const**

Get the disk model.

**Parameters:**

- **diskname**

  Specify the disk name, should be an absolute path such as /dev/sda

**Return value:**

- **QString**

  Disk model

**QString getDiskSerial (const QString diskname) const**

Get the disk serial number.

**Parameters:**

- **diskname**

  Specify the disk name, should be an absolute path such as /dev/sda

**Return value:**

- **QString**

  Disk serial number

**unsigned int getDiskPartitionNums (const QString diskname) const**

Get the number of sub-partitions under the disk/partition.

**Parameters:**

- **diskname**

  Specify the disk name, should be an absolute path such as /dev/sda

**Return value:**

- **unsigned int**

  Number of sub-partitions under this disk/partition

**QString getDiskType (const QString diskname) const**

Get the disk type.

**Parameters:**

- **diskname**

  Specify the disk name, should be an absolute path such as /dev/sda

**Return value:**

- **QString**

  Disk type, SSD or HDD or Hybrid

**QString getDiskVersion (const QString diskname) const**

Get the disk firmware version information.

**Parameters:**

- **diskname**

  Specify the disk name, should be an absolute path such as /dev/sda

**Return value:**

- **QString**

  Firmware version information

**unsigned long long getDiskSectorNum (const QString diskname) const**

Get the number of disk sectors.

**Parameters:**

- **diskname**

  Specify the disk name, should be an absolute path such as /dev/sda

**Return value:**

- **unsigned long long**

  Number of sectors

## EXAMPLE USAGE

```
#include <kysdkdbus.h>
#include <QCoreApplication>
int main(int argc, char *argv[])
{
    QCoreApplication app(argc, argv);
    KySdkDisk diskInfo;
    // Get disk list
    QStringList disks = diskInfo.getDiskList();
    // Get information of the first disk
    if (!disks.isEmpty()) {
        QString diskName = disks.first();
        QString model = diskInfo.getDiskModel(diskName);
        double size = diskInfo.getDiskTotalSizeMiB(diskName);
        // ... use other methods
    }
    return 0;
}
```
