Here's the basic approach:
1. Write an `extern(C)` function in D.
2. Write a corresponding declaration of that function in C
(typically, in a header file).
3. Use your D and C compilers to separately compile your D and C
source files, respectively.
4. Use your D compiler to link the resulting object files.
For example, given these source files:
extern(C) void hello()
import std.stdio: writeln;
writeln("Hello from D!");
...you can compile them with the following commands:
$ dmd -c lib.d # produces lib.o
$ gcc -c main.c # produces main.o
$ dmd main.o lib.o # produces main
You should now be able run `./main` and see it print "Hello from
