I suspect there is a bug in getaddrinfo on Mac OS X 10.6.4. At least,
the behavior of the following program is incompatible with that on Mac
OS X 10.5.8.
#include <stdio.h>
#include <string.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netdb.h>
main ()
{
struct addrinfo hints, *res;
char *servnames[] = {"0", "1", NULL};
int error, i;
memset (&hints, 0, sizeof (hints));
hints.ai_family = PF_UNSPEC;
hints.ai_socktype = SOCK_STREAM;
for (i = 0; i < sizeof (servnames) / sizeof (servnames[0]); i++)
{
if (servnames[i])
printf ("servname = \"%s\":\n", servnames[i]);
else
printf ("servname = (null):\n");
error = getaddrinfo ("localhost", servnames[i], &hints, &res);
if (error != 0)
puts (gai_strerror (error));
else
{
struct addrinfo *r;
for (r = res; r; r = r->ai_next)
{
printf ("family = %d, socktype = %d, protocol = %d\n",
r->ai_family, r->ai_socktype, r->ai_protocol);
}
freeaddrinfo (res);
}
puts ("");
}
}
*** Mac OS X 10.6.4 ***
servname = "0":
nodename nor servname provided, or not known
servname = "1":
family = 30, socktype = 1, protocol = 6
family = 30, socktype = 1, protocol = 6
family = 2, socktype = 1, protocol = 6
servname = (null):
family = 30, socktype = 1, protocol = 6
family = 30, socktype = 1, protocol = 6
family = 2, socktype = 1, protocol = 6
*** Mac OS X 10.5.8 ***
servname = "0":
family = 30, socktype = 1, protocol = 6
family = 30, socktype = 1, protocol = 6
family = 2, socktype = 1, protocol = 6
servname = "1":
family = 30, socktype = 1, protocol = 6
family = 30, socktype = 1, protocol = 6
family = 2, socktype = 1, protocol = 6
servname = (null):
family = 30, socktype = 1, protocol = 6
family = 30, socktype = 1, protocol = 6
family = 2, socktype = 1, protocol = 6
Actually, one can find a major rewrite in getaddrinfo's
implementation. (Libinfo in
http://opensource.apple.com/release/mac-os-x-1064/ and
http://opensource.apple.com/release/mac-os-x-1058/ )
