= FFI Talk

These are the slides and the example code I used in
my FFI lighting talk. Broadly the examples assume
a POSIX operating system and the S.M.A.R.T. example
assumes Linux but could be ported elsewhere easy 
enough. Be careful, the examples are arranged to fit
on a projector screen more than correctness:)

== Examples

=== hello_world

Simple hello world example

=== hello

Example passing params to C function

=== inet_checksum

Example using pointers and semi-realistic computation

=== getpid

libc example that gets the current process id

=== S.M.A.R.T.

Native code returns pointers to structs containing
hard drive diagnostic information (Linux specific)

== Presentation
