[Openmcl-devel] Accessing foreign #define'd constants

I'm trying to write a littl FFI to ioctl(2). As one of its arguments,
it requires some sort of control constant, e.g. BIOCSETIF, which is
#define'd in <net/bpf.h>. Is there I way I can access constants like
these directly, or do I have to figure what number is the value of
BIOCSETIF, and use that number? Clearly the former is more portable,
since the number used might be different under different library
implementations (which probably isn't much of a worry in fact, though
in principle it is).
If this sort of thing is covered in the documentation, I apologize in
advance for the trouble.
If there is not a way to do this currently, is there a possibility of
adding such capability? I would be interesting in adding it, if it's
not supporte. I'm new to openmcl-ffi, though, so, the learning curve
might initially delay the result.
