[ANN] FFI Tutorial, Pharo5 / Libclang

hi all,

Just announcing that I'm writing a series of posts on using FFI in
Pharo 5 to interface to libclang, the interface library for the LLVM C
compiler.

http://blog.openinworld.com/2016/09/pharo-libclang-ffi-part-1-preamble/

I'm writing this from the perspective of a FFI newbie progressively
learning the system. I've left in a few mis-steps since I think it
can be useful seeing what didn't work.

cheers -ben

Did you let

LibC class >> ticksSinceStart
^ self ffiCall: #( uint clock () ) module: LibC
and in Playground inspect following…

FFIPlay ticksSinceStart
"==> 32709046 (or something similar)"

FFIPlay on purpose? It was unclear to me how this is related to LibC

An error. Thanks for picking that up. When I first was trying it I
had created that class to hold experiements, but it wsa shorter for
the post to put in on the existing class.
