Export a function that calls this:
And also export a function that calls this:
And tell the user to call those when they load/unload the
library. (It is pretty common for C libraries to require explicit
init/term calls so they should be used to it.)
They refcount internally so it is ok to call multiple times, just
make sure the init and term are always paired.
(btw the druntime actually exports them as extern(C)
rt_init/rt_term but I'd still recommend you do your own anyway.
if you do have extra work to do you can just do it there, and it
can use whatever your lib naming conventions are. and besides im
not sure if the extern(C) things are specified stable (even
though they have been for as long as i can remember), whereas
doing your own thing that `import core.runtime; return
Runtime.initalize;` is. )
