[Pharo-users] NativeBoost external structure with char[] rather than char*

I am looking for some NativeBoost advice on the best way of using a structure with an containing a char array like the following: int level int number char[256] msgText ulong elapsedTime Currently I am using an NBExternalAddress returned by NativeBoost>>allocate: because the external library holds onto the address and using byteAt: to see what is going on in the structure while I get used to the external library API. I can think of a couple of options, create my own NBExternalType subclass which I can use in an NBExternalStructure or subclass NBExternalAddress/Object with methods to extract the appropriate data, or have I missed the simple solution? Thanks, Guy
