The other day I had some questions about using CCALL. While the Julia code was MWE the C code needed 25Gb of data !

As a beginner to interfacing with C libraries I thought I would build some MWE examples to enable me to check my assumptions and not be fighting both the C code and the Julia while trying to learn.

I hope this might be useful for others in my footsteps.

As I am learning myself, I would fully welcome anyone else’s contributions to this, should anyone feel inclined. I certainly am likely to make mistakes.

Matt

I wish for more example for the opposite, having `Julia` code embedded in `C`.

This time last week I had never used ccall
