Hi all,
I have been working on shared memory. I have created the shared memory and a linked list of 5 nodes. Now I want to attach the linked list to shared memory. When we attach a shared memory it returns a void pointer, but here I am in a fix , how to relate this void pointer to linked list.... (4 Replies)
i have a linked list set up like
typedef struct client_list {
char *client_name;
int client_socket_fd;
struct client_list *next;
} client;
client *client_list=NULL;
before adding to the list i check if it already exists, only if it does not then i add
if (client_list==NULL... (1 Reply)
Hi, I am programming in kernel, and I want to use a double linked list that holds infos that every process could access and modify THIS list. So, I suppose it is a 'global' variable since every process(thread) can reach it, I am wondering where to put it? by changing some of the kernel files? (1 Reply)

ares_set_servers
ARES_SET_SERVERS(3) Library Functions Manual ARES_SET_SERVERS(3)NAME
ares_set_servers - Initialize an ares_channel name servers configuration
SYNOPSIS
#include <ares.h>
int ares_set_servers(ares_channel channel, struct ares_addr_node *servers)
DESCRIPTION
The ares_set_servers(3) function initializes name servers configuration for the channel data identified by channel, from a servers pointer
to a linked list of ares_addr_node structs holding name servers address data.
The name server linked list pointer argument may be the result of a previous call to ares_get_servers(3) or a linked list of ares_addr_node
structs setup by other means.
This function replaces any potentially previously configured name servers with the ones given in the linked list. So, in order to configure
a channel with more than one name server all the desired ones must be specified in a single list.
ares_set_servers(3) does not take ownership of the linked list argument. The caller is responsible for freeing the linked list when no
longer needed.
This function is capable of handling IPv4 and IPv6 name server addresses simultaneously, rendering ares_init_options(3) with optmask
ARES_OPT_SERVERS functionally obsolete except for IPv4-only name server usage.
RETURN VALUES ares_set_servers(3) may return any of the following values:
ARES_SUCCESS The name servers configuration was successfuly initialized.
ARES_ENOMEM The process's available memory was exhausted.
ARES_ENODATA The channel data identified by channel was invalid.
ARES_ENOTINITIALIZED
c-ares library initialization not yet performed.
