KDK_GET_HARD_DISK(3)       Library Functions Manual       KDK_GET_HARD_DISK(3)

NAME
       kdk_get_hard_disk - <?><?><?><?><?><?><?><?><?><?>

SYNOPSIS
       #include <libkydiskinfo.h>

       extern char** kdk_get_hard_disk();

       Link with -lkydiskinfo.

Detailed Description
       The kdk_get_hard_disk() function obtains the system access hard disk
       list information during the call process.

RETURN VALUE
       The return value is a char** type, with each string representing the
       absolute path of a disk and ending with a NULL character.

       After completion, kdk_free_disklist() function releases a list of disk
       information.
