Force Sleep causes memory leak in IOBluetoothGetVersion() ?

Hi all,

The program below prints "...autoreleased with no pool in place..."-messages every time my Mac wakes from Force Sleep while the program is running. This leaves me with two questions: 1. Why would sleep/wake want to release objects in my application? 2. How do I fix this memory leak - need I create an AutoreleasePool?

I'm running Mac OS X 10.3.5.

Any help is much appreciated!
Mark


My program:
------------
#include <CoreFoundation/CoreFoundation.h>
#include <IOBluetooth/IOBluetoothUserLib.h>

int main ()
{
    BluetoothHCIVersionInfo hwVersion;
    IOReturn ioRet = IOBluetoothGetVersion(NULL, &hwVersion);
    if (ioRet != kIOReturnSuccess)
    {
        fprintf(stderr, "No Bluetooth hardware found, error=0x%8x\n", ioRet);
        return 1;
    }

    fprintf(stderr, "Bluetooth hardware detected\n");
    CFRunLoopRun();
    return 0;
}

I compile it with:
----------------
cc bttest.c -framework CoreServices -framework IOBluetooth -o bttest

Here's the output: ---------------- Bluetooth hardware detected 2004-11-05 21:16:28.824 bttest[2458] *** _NSAutoreleaseNoPool(): Object 0x50a870 of class NSIdEnumerator autoreleased with no pool in place - just leaking 2004-11-05 21:16:28.826 bttest[2458] *** _NSAutoreleaseNoPool(): Object 0x50c570 of class IOBluetoothNotification autoreleased with no pool in place - just leaking 2004-11-05 21:16:28.828 bttest[2458] *** _NSAutoreleaseNoPool(): Object 0x501d70 of class NSCFArray autoreleased with no pool in place - just leaking 2004-11-05 21:16:38.766 bttest[2458] *** _NSAutoreleaseNoPool(): Object 0x509a70 of class NSIdEnumerator autoreleased with no pool in place - just leaking 2004-11-05 21:16:38.767 bttest[2458] *** _NSAutoreleaseNoPool(): Object 0x50c570 of class IOBluetoothNotification autoreleased with no pool in place - just leaking 2004-11-05 21:16:38.767 bttest[2458] *** _NSAutoreleaseNoPool(): Object 0x50c840 of class NSCFArray autoreleased with no pool in place - just leaking _______________________________________________ Do not post admin requests to the list.
