C to Ada

Hi,

How do you map something like this to Ada (for a binding)?  It's 
probable that I'll only be working with GNAT on the Linux front (it's 
all there is), so a GNAT specific option although not ideal, is acceptable.


/* Open the shared object FILE and map it in; return a handle that can 
be passed to `dlsym' to get symbol values from it.  */

extern void *dlopen (__const char *__file, int __mode) __THROW;

I know rougly how to map the __file, and __mode params but am not sure 
how to deal with the void * or in this case the throw.  This is taken 
from dlfcn.h which is the header for dynamic library support in Linux. 
If anyone already has a (GMGPL) binding to this library and they'd like 
to share, please let me know, it'll save me making one.  In any event 
how do you translate this C code so it can be called from Ada?

After I get a wee thin binding working, I'm going to make it a little 
thicker and toss it into the open.


Cheers,
Chris
