## f_getlabel

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

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

#### Parameters

path
