Using the HP-UX libIO Library

instance, my_string, driver_name , state, type);

/*end of libIO operations */

io_end();

}

Output

class instance hardware path driver name state type

disk 25 1/0/1/0/0/1/1.6.0 sdisk CLAIMED DEVICE

Example 3

Get all disk devices from the legacy kernel I/O data structure and print the class

name, instance, hardware path and driver names.

Algorithm

1. Initialize the libIO library.

2. Search for all disk devices in the legacy kernel I/O data structures.

3. Get the class name, instance number, hardware path, and driver name of this

disk device and print them.

4. Terminate the connection.

Solution

#include <sys/libIO.h>

#include <stdio.h>

#define RETURN_NODE_NUMBER 500

main()

{

io_token_t token, ret_token[RETURN_NODE_NUMBER];

io_token_t node;

hw_path_t hw_path;

int instance;

char *key[12];

void *ptr[12];

int i=0;

char state[MAX_NAME_LEN];

char *driver_name;

char *class_name;

char type[MAX_NAME_LEN];

char my_string[MAX_HW_PATH_STR];

driver_name=(char *)malloc(MAX_NAME_LEN);

class_name=(char *)malloc(MAX_NAME_LEN);

strcpy(driver_name, "sdisk");

strcpy(class_name , "disk");
