Well, you should get meaningful data with the appropriate data() method - if not, you are doing something else wrong.  The problem is that this data /becomes/ invalid as soon as the original object - where you called data() upon - gets out of scope. So if you need to *keep* this data, as returned by data(), then you need to "memcpy" it into your own array (with the usual caveats of buffer overflows etc.)

Cheers, Oliver
