Ronie is working on unifying all the api and proposing one syntax mechanism for

������ - FFI

The FFI situation is not good and we know we should improve it.

Some of the comments might still hold. For the time: ���05:45��� code to work, you would need FFI to handle all the hassle of memory management and actually allocate the memory for 5 characters and copying it. I never used FFI but I doubt it does this.

Looking at FFI library, you both have ExternalAddress (for the struct with char*) and ExternalType (for the struct with char[5]) that you can use. For the later solution, it still looks like you should define a specific 5 bytes ArrayOf5Char type.

I can���t use NativeBoost on the Raspberry, I would be glad if I could !!!
