[ENet-discuss] How to get our local IP?

[Ruud van Gaal]

Hi Martin,

A simple way might be:

  char name[MAXHOSTNAMELEN];
  struct sockaddr_in addr;

  gethostname(name,sizeof(name));

  struct hostent *hostEntry=0;
  struct in_addr ia;

  // From the Unix network FAQ (www.unixguide.net/network/socketfaq/)
  // First try it as aaa.bbb.ccc.ddd.
  ia.s_addr=inet_addr(name);
  if(ia.s_addr!=INADDR_NONE)
  {
    // Got it...
    addr.sin_addr.s_addr=ia.s_addr;
    return TRUE;
  }
  // Next, try just gethostbyname()
  hostEntry=gethostbyname(name);
  if(hostEntry)
  {
    addr.sin_addr.s_addr=*(int*)hostEntry->h_addr_list[0];
    return TRUE;
  }

  if(!hostEntry)
  {
    qnError("QNAddress:GetByName(%s) failed",name);
    return FALSE;
  }
  // Retrieve address (IPv4)
  addr.sin_addr.s_addr=*(int*)hostEntry->h_addr_list[0];

May require some tuning to your code context.

Cheers,
Ruud
