I am not sure if this is a problem unique to me or not but under 10.5
[[NSHost currentHost] name] or [[[NSProcessInfo] processInfo]
hostname] were quick and easy ways to get an mDNS friendly hostname
such as imac-2.local
On 10.6 I find that both these combinations block badly (NSProcessInfo
merely defers to NSHost I think).
The list has a few references to the possibility of these blocking but
I never encountered it until now.
According to a stack sample getnameinfo() seems to be the library call
that is blocking.
_mdns_query_mDNSResponder seems to be the actual blocking call.
Anyone else seeing this behaviour?
There seem to be two alternatives:
NSString *name = NSMakeCollectable(SCDynamicStoreCopyLocalHostName
(NULL));
This gives the correct mDNS friendly hostname but omits the local
pseudo domain.
Otherwise this seems suitable:
char hostname[_POSIX_HOST_NAME_MAX + 1];
gethostname(hostname, _POSIX_HOST_NAME_MAX);
name = [NSString stringWithCString:hostname
encoding:NSUTF8StringEncoding];
