I would normally agree as I tend to hate typedefs ($DAYJOB {ab,mis}uses
them way too much), and your way was what I wrote at first, but Rob Clark's
typedef idea makes it much harder for someone to allocate a buffer of
the wrong size, which IMO is good thing here.

I can rewrite the typedef out if you think it's better.
