KDK_USB_GET_LIST(3)        Library Functions Manual        KDK_USB_GET_LIST(3)

NAME
       kdk_usb_get_list - <?><?><?><?>usb<?><?><?><?>

SYNOPSIS
       #include <libkyusb.h>

       extern pDriverInfoList kdk_usb_get_list();

       Link with -lkyusb.

Detailed Description
       The main function of the interface is to obtain the external usb device
       information.

RETURN VALUE
       On success, returns a pointer to a pDriverInfoList structure containing
       usb information.

       The pDriverInfoList structure is defined in <libkyusb.h> as follows:

                   typedef struct driver_list
                   {
                       struct driver_info *data;
                       struct driver_list *next;
                   } DriverInfoList, *pDriverInfoList;

                   typedef struct driver_info
                   {
                       char name[32]; //<?><?>
                       char type[2 + 1]; //<?><?>
                       char pid[4 + 1];
                       char vid[4 + 1];
                       char serialNo[32]; //<?><?><?>
                       char devNode[32]; //<?><?>
                   } DriverInfo, *pDriverInfo;

       On error, return NULL.

EXAMPLES
       #include "stdio.h"
       #include "libkyusb.h"

       int main()
       {
           pDriverInfoList list = kdk_usb_get_list();
           if(list)
           {
               pDriverInfoList tmp = list;
               while (tmp)
               {
                   printf("Name: %s",tmp->data->name);
                   printf("Class: %s",tmp->data->type);
                   printf("PID: %s",tmp->data->pid);
                   printf("VID: %s",tmp->data->vid);
                   printf("Serial: %s",tmp->data->serialNo);
                   printf("DevNode: %s0,tmp->data->devNode);
                   tmp = tmp->next;
               }

           }
           kdk_usb_free(list);
           return 0;
       }
