At a first glance it looks okay but unless we know what you are going to
do with these data structures it's hard to tell if it is really the best
"translation".

`PF.buffer` might be better a string or an `array.array`.  And is `BLOCK`
really just a structure with *one* member?  Looks a bit odd IMHO.
