Thank you for the example, Mike!
And thanks to all others who support me with their answers! I
didn't expect so much answers, the D community seems to be very
helpful :)
But there still is one thing, which I don't get:
If I "import foo;" in my project, it will be compiled alongside.
So there is no need for an extra library. Same should be for
wrapfoo.d. If I "import wrapfoo;", I should just need the
C-library "foo", and no D-library "food" right?
To have a more practical example, I looked up the "header" of the
GtkD gtk/Main.d file. There are functions exactly like you
described:
public static void init(ref string[] argv)
{
int argc = cast(int)argv.length;
char** outargv = Str.toStringzArray(argv);
gtk_init(&argc, &outargv);
argv = Str.toStringArray(outargv, argc);
}
This function wraps the C-like gtk_init function to a D init
function.
The gtk_init function is the function from the GTK+ library,
which is loaded in the gtkc/gtk.d file:
Linker.link(gtk_init, "gtk_init", LIBRARY.GTK);
Linker and link are defined in the gtkc/Loader.d
So, why is it not enough just to "import gtk.Main"? What kind of
code is inside the gtkd-3 library?
