Greetings,
Okay, gotta Poka-yoke my code.
So I reworked my code like so....
- (void)newConnection:(NSNotification *)notification
{
NSDictionary *userInfo = [notification userInfo];
NSFileHandle *remoteFileHandle = [userInfo
objectForKey:NSFileHandleNotificationFileHandleItem];
NSNumber *errorNo = [userInfo objectForKey:@"NSFileHandleError"];
if( errorNo )
{
NSLog(@"NSFileHandle Error: %@", errorNo);
return;
}
........
When I attempt to connect to a used port I log...
2006-12-27 11:41:24.749 xxxxxx[4814] NSFileHandle Error: 38
The docs say about NSFileHandleError....
"An NSNumber object containing an integer representing the UNIX-type
error which occurred."
Where can I find a meaningful representation of the UNIX-type errors.
Thanks,
- Brian
