They both return 4, and both short and int16_t return 2.
Also, I've noticed that if I use a struct (of four ints) instead, the
same thing happens, the parameters are not correct. And yes, of course
they are extern already.
AFAIK 'int' in D is always a 32-bit value. But in C, 'int' could be
64bit on 64bit platforms. You could try printing sizeof(int) in C and
compare that to int.sizeof in D and see if they match. You probably
know this, but make sure your exported D function is annotated with
extern(C).
All right, found something really odd today, might be a bug. If in C I
have this:
int16_t D_getPictureCoordX(int Pool, int Card);
And in D I have this:
short D_getPictureCoordX(int Pool, int Card);
When I call D_getPictureCoord() from C, the parameters are all off, it
seems that it receives eit
Oh, never mind. About sending strings, I got it working, I just had to
create a function like this in D:
immutable(char)* GetString()
{
return StringD.toStringz();
}
As for D not compiling, I had to declare it in D, d'oh :D And that
extern is in the wrong place there.
All right, I solved that part of the problem by creating a linked
list. However, getting the string out of D is still problematic,
namely because toStringz() gives me an immutable char*, and I don't
seem to be able to pass those, since I can't assign those to immutable
variables outside their const
Hmm, if I was to do it from C, I would have to deal with all the
allocation, since I don't know how large the array is going to be when
it's complete, while D doesn't need to know since it uses dynamic
arrays.

Is it possible to write a static library in D and then use it in a program
written in C? I've found instructions about using DLLs here on the website,
but there is no mention about using static libraries instead.
Also, is it possible to use the same method on Linux, just with .a files
instead? Or
