NAME
       kdk_get_diskinfo - <?><?><?><?><?><?><?><?><?><?><?>

SYNOPSIS
       #include <libkydiskinfo.h>

       extern kdk_diskinfo *kdk_get_diskinfo(const char *diskname);

       Link with -lkydiskinfo.

Detailed Description
       Based on the specified disk name diskname, such as absolute path such
       as /dev/sda, or kdk_get_disklist() function returns an element from a
       value to obtain disk information.

RETURN VALUE
       kdk_diskinfo is a structure that stores disk information, as follows:

       typedef struct _kdk_diskinfo{
           char *name;     // <?><?><?><?>
           char *vendor;   // <?><?><?>
           char *model;    // <?><?>
           char *serial;   // <?><?><?>

           kdk_disk_type disk_type;  // <?><?><?><?><?><?><?> or <?><?> or
       <?><?>
           kdk_disk_interface_type inter_type;   // <?><?><?><?>
           unsigned int rpm;  // <?><?><?><?><?><?><?><?><?><?><?><?><?><?><?>

           unsigned long long sectors_num;   // <?><?><?><?>
           unsigned int sector_size;   // <?><?><?><?><?><?><?><?>
           float total_size_MiB;  // <?><?><?><?><?>MiB<?><?><?>

           unsigned int partition_nums; //
       <?><?><?>/<?><?><?><?><?><?><?><?><?>
           char *uuid;     // UUID
           short mounted;   // <?><?><?><?><?>
           char *mount_path;   // <?><?><?><?>
           kdk_disk_format format; // <?><?><?><?><?>
           kdk_disk_partition_type part_type;  // <?><?><?><?>
           char *fwrev;    //<?><?><?><?><?><?>

       }kdk_diskinfo;
