Yes, I've just found it as well, it was the reason, thanks anyway.

Found my error, change "" to NULL make the deal! getaadrinfo can't
read "" service.

Why should it recognize the "" service? Give it the service you want
to use, or NULL.

[OpenWrt-Devel] getaddrinfo breaks with IPV6 and IPV4

2015-08-06 Thread Baptiste Clenet 
Hi,

I try to use getaddrinfo() function and I send as parameters:

  static char addrstr[256] = "::1";
  struct addrinfo *res, *ainfo;
  struct addrinfo hints;
  memset ((char *)&hints, 0, sizeof(hints));
  hints.ai_socktype = SOCK_DGRAM;
  hints.ai_family = AF_UNSPEC;

  int error = getaddrinfo(addrstr, "", &hints, &res);

  if (error != 0) {
fprintf(stderr, "getaddrinfo: %s\n", gai_strerror(error));
return error;
  }


And it gives me:
getaddrinfo: Unrecognized service

I tried with an IPV4 address, same problem. Do you know which
implementation of getaddrinfo OpenWRT use?

Regards,
