>Description:
When using getaddrinfo with AI_NUMERICHOST set in the options field of
the hints structure, and passing a non-numeric host name, EAI_NODATA is
returned. RFC 2553 requires an error code of EAI_NONAME in that case though,
and this is what the getaddrinfo man page also says (in fact it's the same
text).
>How-To-Repeat:
#include <stdlib.h>
#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netdb.h>
#include <netinet/in.h>
int
main(int argc, char *argv[]) {
struct addrinfo ai_hints;
struct addrinfo *ai_res;
int ai_retval;
memset(&ai_hints, 0, sizeof ai_hints);
ai_hints.ai_family = PF_UNSPEC;
ai_hints.ai_socktype = SOCK_STREAM;
ai_hints.ai_protocol = IPPROTO_TCP;
ai_hints.ai_flags = AI_NUMERICHOST;
ai_retval = getaddrinfo("host.example.net", "9", &ai_hints, &ai_res);
printf("getaddrinfo returned %d, should be %d (EAI_NONAME).\n",
ai_retval, EAI_NONAME);
(void) argc;
(void) argv;
return EXIT_SUCCESS;
