VC Get computer Name and IP address method _c language

This article describes the VC to obtain the computer name and IP address method. Share to everyone for your reference. The implementation methods are as follows:

#include <winsock2.h> 
#include <stdio.h> 
#pragma comment (lib, "Ws2_32.lib")
void Main () 
{ 
wsadata wsadata; 
WORD dwversionrequested; 
int err; 
Err=wsastartup (dwversionrequested,&wsadata); 
Char hostname[128]; 
if (GetHostName (hostname,128) ==0) 
{ 
  printf ("%s\n", hostname);//Computer name 
} 
char buf[20];
memset (buf,0,80);
struct Hostent *phost = gethostbyname (hostname);
for (int i = 0; Phost!= null && phost->h_addr_list[i]!= null; i++) 
{  
  //put it in a character array for easy application
  strcpy (bu F,inet_ntoa (* (struct in_addr *) phost->h_addr_list[i));
  Inet_ntoa (* (struct in_addr *) phost->h_addr_list[i]);
  IP address
  printf ("%s\n", buf);
} 
WSACleanup (); 
}

I hope this article on the VC program for everyone to help.
