Thanks x 4!

As a most obvious mistake I thank you for the kind corrections I got. This
of course solved my problem. Only sad thing is that was not what I really
wanted to do. What I really wanted to do was:

CFStringRef ServiceName =
IOBluetoothSDPServiceRecordGetServiceName(HIDServiceRecord));

I get "EXC_BAD_ACCESS" here, and I'm guessing I'm still doing some basic
fault. The definition of "IOBluetoothSDPServiceRecordGetServiceName"

extern CFStringRef IOBluetoothSDPServiceRecordGetServiceName(
    IOBluetoothSDPServiceRecordRef serviceRecord)

Anyone got some wisdom to share?

Try changing the CFDictionaryGetValueIfPresent call to:
CFDictionaryGetValueIfPresent (
                  myServiceDict,
                  CFSTR("0100 - ServiceName*"),
                  &value

Well strange to me anyway...
I have a problem accessing the values in my CFDictionary that I have created
from a .plist file. I can get all keys and values by using the "
CFDictionaryGetKeysAndValues" function but when using
"CFDictionaryGetValueIfPresent" I get "EXC_BAD_ACCESS". I appreciate any
kind of help. This is more or less what I'm doing:
CFDictionaryRef             myServiceDict;
myServiceDict = CreateMyDictionary();
/* reads a plist file, based on CreateMyPropertyListFromFile found in the
" Property List Programming Topics for Core Foundation" */
// This works
    CFStringRef keys[100], values[100];
    CFDictionaryGetKeysAndValues (
   myServiceDict,
   keys,
   values
);
// and I can use my dict to correctly do this:
    result = IOBluetoothAddServiceDict( myServiceDict, &HIDServiceRecord);
// result is kIOReturnSuccess on return
// But this crashes, although I have confirmed that "0100 - ServiceName*" is
a key in the CFDictionary
CFStringRef value;
    Boolean jom_test =
    CFDictionaryGetValueIfPresent (
    myServiceDict,
   "0100 - ServiceName*",
   &value
);
If I could get some input here it would make my day!
Thanks! / Johan
