KDK_NET_GET_HOSTS_DOMAIN(3)

📦 version 3.0.1.4, in arch rolling, ubuntu resolute, ubuntu stonking

🎀 KDK_NET_GET_HOSTS_DOMAIN 🎀

okay bestie, welcome to the KDK_NET_GET_HOSTS_DOMAIN(3) page — it lives in the Library Functions Manual, and it's literally the shortest little glow-up in the whole kynetinfo friend group. let's get into it 💖

✨ NAME ✨

kdk_net_get_hosts_domain — 获取hosts配置的域名映射

(that's "grab the domain name mapping that hosts configured", for anyone whose Chinese is lowkey on vacation 🫶)

🌸 SYNOPSIS 🌸

#include <libkynetinfo.h>

extern char* kdk_net_get_hosts_domain();

and don't forget to link with -lkynetinfo, periodt 💅

🦋 Detailed Description 🦋

so the main character function of this interface is getting the domain name mapping configured by hosts. that's the whole vibe. that's the job. she's simple, she's effective, she slays 💖

👑 RETURN VALUE 👑

  • on success — she hands you the domain name mapping configured by hosts, type char *. but listen: the returned string needs to be released by free — she's not gonna clean up after herself, bestie, that's on you 🙈
  • on error — return NULL.

🌈 EXAMPLES 🌈

here's a whole main function showing her off (and her whole friend group tagging along, ngl they ate):

#include "libkynetinfo.h"
#include "stdio.h"
#include "stdlib.h"

int main(int argc, char *argv[])
{
    prouteMapList list = kdk_net_get_route(), tmp = list;
    while (tmp)
    {
        printf("%s default route %s0, tmp->name, tmp->addr);
        tmp = tmp->next;
    }
    kdk_net_free_route(list);
    if (argc < 2)
        printf("please input test port num0);
    else
        printf("port:%s's state %d0, argv[1], kdk_net_get_port_stat(atoi(argv[1])));

    pChain chain = kdk_net_get_iptable_rules();
    pChain tmpchain = chain;
    while(tmpchain)
    {
        printf("Chain: %spolice: %s0,tmpchain->total,tmpchain->policy);
        pChainData tmpData = tmpchain->data;
        if(tmpData)
            printf("target: %sprot: %sopt: %ssource: %sdestination: %soption: %s0,tmpData->target,tmpData->prot,tmpData->opt,
                                tmpData->source,tmpData->destination,tmpData->option);
        printf("0);
        tmpchain = tmpchain->next;
    }
    kdk_net_free_chain(chain);

    int result[65536];
    int net = kdk_net_get_multiple_port_stat(0, 1000, result);
    if(net == 0)
    {
        size_t count = 0;
        for(;count < 1000 ;count++)
        {
            printf("%d", result[count]);
        }
    }
    else
        printf("Failed With %d", net);
     printf("0);

    char mask[32] = " ";
    kdk_net_get_netmask("enaftgm1i0", mask);
    printf("mask = %s0, mask);

    char **port = kdk_net_get_proc_port();
    size_t index = 0;
    while(port[index])
    {
        printf("No.%ld, port = %s0, index+1, port[index]);
        index++;
    }
    kdk_net_freeall(port);

    port = kdk_net_get_up_port();
    index = 0;
    while(port[index])
    {
        printf("No.%ld, port = %s0, index+1, port[index]);
        index++;
    }
    kdk_net_freeall(port);

    char *hosts = kdk_net_get_hosts();
    if (hosts != NULL)
    {
        printf("hosts = %s0, hosts);
        free(hosts);
    }

    char *domain = kdk_net_get_hosts_domain();
    if (domain != NULL)
    {
        printf("domain = %s0, domain);
        free(domain);
    }

    char **resolv = kdk_net_get_resolv_conf();
    index = 0;
    while(resolv[index])
    {
        printf("No.%ld, resolv = %s0, index+1, resolv[index]);
        index++;
    }
    kdk_net_freeall(resolv);
    return 0;
}

see that kdk_net_get_hosts_domain() block in the middle? that's our girl ✨ she gets the domain, checks it's not NULL, prints it, and then free(domain) — no leaks, no drama, main character energy fr fr 👑

💜 CONFORMING TO 💜

these functions are as per the withdrawn POSIX.1e draft specification. and then the following functions are Linux extensions (iykyk):
