Uhm. Quite a lot solutions for a simple task :P I asked the question,
because I found a bug in OracleClient, where memory was allocated but
not zeroed (and OCI expected it to be padded with 0's). So a simple
AllocHGlobal was not enough. I am working with the current repository
version - is there a _preferred_ way? For now I am going to run a
benchmark and choose the fastest method :-)
