So just add the declaration to your D file:

extern(C) void myCfunction(FILE* stream);

I do have a similar declaration in D. It appears the problem is that the C program I'm trying to convert passes stdout as the argument and the D compiler complains somewhat like the following:

Error: function foo.main.myCfunction (shared(_IO_FILE)* stream) is not callable using argument types (File)

So I guess the question is what to pass instead of stdout.

Hmm, calling e.g. fprintf with stdout should just work:

---
void main()
{
    import core.stdc.stdio;
    fprintf(stdout, "Hello %s", "world".ptr);
}

Could you maybe provide your whole code?
