I am using the C API of IOBluetooth in Mac OS X v10.3.9 (Apple Bluetooth 1.5.4) and Mac OS X v10.4.2 (Apple Bluetooth 1.6.0). If I pass a pointer for 10 byte long memory to IOBluetoothGetVersion's hardware attribute, all 10 bytes are used. According to the struct BluetoothHCIVersionInfo in Bluetooth.h only 8 byte should be used. The data fields return correct values for all of my Bluetooth modules but in between there are two wired bytes which are not listed in the struct. I know I should rather report a bug but because I am in a quite esoteric IDE and I do not write C but use a bridge at the moment (long story), I would rather check this first here on the list. Workaround: If you do not need the hardware information, pass NULL to this optional parameter and it works. In this case you get the software version, double check if you rather need weak linking. If you need hardware information, first check if IOBluetoothLocalDeviceAvailable is not enough. If you really, really need the hardware information, use 10 byte memory (patch the struct in Bluetooth.h or better overwrite in code). _______________________________________________ Do not post admin requests to the list.
