i done that program to get a only one subnet mask address from system and display..

i refer from the msdn website. my coding is:

C++

#include <stdafx.h>
#include <windows.h>
#include <iphlpapi.h>
#include <stdio.h>
#include <stdlib.h>
#pragma comment(lib, &quot;Iphlpapi.lib&quot;)
int main(void)
{
    ULONG            cbBuf    = 0;
    PIP_ADAPTER_INFO pAdapter = NULL;
    PIP_ADAPTER_INFO pMemory  = NULL;
    DWORD            dwResult = 0;
    PIP_ADAPTER_INFO pMemory1 = NULL;
    dwResult = GetAdaptersInfo(NULL, &amp;cbBuf);
    pMemory = pAdapter = (PIP_ADAPTER_INFO) malloc(cbBuf);
    dwResult = GetAdaptersInfo(pAdapter, &amp;cbBuf);
    while (pAdapter)
    {
        printf("Name: %s\nDescription: %s\nGateway: %s\nSubnet Mask: %s\n",
               pAdapter-&gt;AdapterName,
               pAdapter-&gt;Description,
               pAdapter-&gt;GatewayList.IpAddress.String,
               pAdapter-&gt;IpAddressList.IpMask.String);
        pAdapter = pAdapter-&gt;Next;
    }
    free(pMemory);
    getchar();
    return 0;
}

like that i created.

i run sucessfully..

but my system i create 4 ip address and equivalent subnet mask address also...

i don't know how to retrieve all subnet mask address form the system using c.

use the adapter function

This should return all your Ethernet Cards details(Includes subnet mask), What are you expecting to see?

PIP_ADAPTER_INFO pAdapterInfo;
PIP_ADAPTER_INFO pAdapter=NULL;
printf("Hello World!\n");
DWORD dwRetVal=0;
ULONG ulOutBufLen=sizeof(PIP_ADAPTER_INFO);
pAdapterInfo = (IP_ADAPTER_INFO *) malloc(sizeof (IP_ADAPTER_INFO));
if(GetAdaptersInfo(pAdapterInfo, &ulOutBufLen)==ERROR_BUFFER_OVERFLOW)
{
free(pAdapterInfo);
pAdapterInfo = (IP_ADAPTER_INFO *) malloc(ulOutBufLen);

}
dwRetVal = GetAdaptersInfo(pAdapterInfo, &ulOutBufLen);
pAdapter = pAdapterInfo;
while (pAdapter)
{
temp=new node();
temp->gate=pAdapter->GatewayList.IpAddress.String;
temp->ip=pAdapter->IpAddressList.IpAddress.String;
temp->mac=pAdapter->IpAddressList.IpMask.String;
temp->next=main1;
main1=temp;
IP_ADDR_STRING *p;
p=(pAdapter->IpAddressList.Next);
while(p)
{
temp=main1;
while(temp->next!=NULL)
{
temp=temp->next;
}
temp=new node();
temp->ip=p->IpAddress.String;
temp->mac=p->IpMask.String;
temp->next=main1;
main1=temp;
p=p->Next;
}

pAdapter=pAdapter->Next;
}
this will provide all ip and subnet mask address you can use it..

100% its working..
