Hello,
I've found several examples of getting the computer Name but
some give warnings about making a pointer from an integer and
they all fail with signal EXC_BAD_ACCESS here
objc_msgSend_vtable5
_NSDescriptionWithLocaleFunc
_CFStringAppendFormatAndArgumentsAux
_CFStringCreateWithFormatAndArgumentsAux
_CFLogvEx
NSLogv
NSLog
Here are three examples I've tried:
1. CFStringRef temp = SCDynamicStoreCopyComputerName (NULL, NULL);
NSString * name = [NSString stringWithString: temp];
return name;
2. CFStringEncoding encoding = kCFStringEncodingUTF8;
CFStringRef name = SCDynamicStoreCopyComputerName (NULL, &encoding);
return name;
3. #import <SystemConfiguration/SCDynamicStore.h>
SCDynamicStoreContext context = {0, NULL, NULL, NULL};
SCDynamicStoreRef store = SCDynamicStoreCreate (kCFAllocatorDefault,
CFSTR("testStrings"),
NULL,
&context);
NSLog(@"SCDynamicStoreCopyLocalHostName() = %@",
SCDynamicStoreCopyLocalHostName(store));
According to the docs CFStringRef is toll-free-bridged with
NSString and so interchangeable. The authors of the examples
cite no issues. Could I have done something to my project to
break toll-free bridging? I confess, I haven't thought about
toll-free bridging since the WebObjects days.
Thanks for any ideas,
Steve
