Because I want to minimise the size of the foreign bindings - this would require C code for every single Netgraph struct. If they were packed, I could just do it all in OCaml.
Packing lead to perfomance issues. So it is used only in case of packet specifications were each bit
may have its own meaning and there place is fixed by protocol which is lang/arch/etc independant
and we cant just add a couple of them.
Isn't this a problem for other language bindings as well, or is everyone doing Netgraph userland hacking in C at the moment?
For Unix programming I do not use other languages than C, except for scripting.
And I believe I am not in minority. IMHO perfomace issue is more important than
cross language interaction which is in minority.
