## f_getlabel

The f_getlabel function returns volume label and volume serial number of a volume.

    FRESULT f_getlabel (
      const TCHAR* path,  /* [IN] Drive number */
      TCHAR* label,       /* [OUT] Volume label */
      DWORD* vsn          /* [OUT] Volume serial number */
    );

#### Parameters

path
  Pointer to the null-terminated string that specifies the logical drive. Null-string specifies the default drive. If a null pointer is given, the function fails with `FR_INVALID_DRIVE`.
label
  Pointer to the buffer to store the volume label. If the volume has no label, a null-string will be returned. Set null pointer if this information is not needed. The buffer size should be shown below at least to avoid buffer overflow.

  Configuration | FF_FS_EXFAT == 0 | FF_FS_EXFAT == 1
  FF_USE_LFN == 0 | 12 items | -
  FF_LFN_UNICODE == 0 | 12 items | 23 items
  FF_LFN_UNICODE == 1,3 | 12 items | 12 items
  FF_LFN_UNICODE == 2 | 34 items | 34 items

vsn
  Pointer to the `DWORD` variable to store the volume serial number. Set null pointer if this information is not needed.

FR_OK, FR_DISK_ERR, FR_INT_ERR, FR_NOT_READY, FR_INVALID_DRIVE, FR_NOT_ENABLED, FR_NO_FILESYSTEM, FR_TIMEOUT
