KDK_GET_HARD_DISK_SIZE(3)

NAME
kdk_get_hard_disk_size - 获取硬盘大小

SYNOPSIS
#include <libkydiskinfo.h>

extern char* kdk_get_hard_disk_size(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_hard_disk() function returns an element in the value to obtain hard disk size information.

RETURN VALUE
On success, returns the hard disk size of type char*, in MIB; The returned string needs to be released by free

On error, return NULL.
