Hi
I am new in D.
I've the following problem. I want to use a old function out of the C
programming language. I'm using D, with the dmd compiler, and the Tango
lib. My "dirty" solution is the following:

<code>
version (Tango) extern (C) int getchar();

void main() {
	char quit = '\0';
	while (quit != 'q') {
		quit = getchar;
	}
}
</code>

But I believe the first line is too inconvenient.
Are there any better solutions to use C functions with the Tango lib.

I'm looking forward to your answers and I would be very happy with a few code exampes.

Greetings from Germany

How about:

----
import tango.stdc.stdio;
----

If you're using tango then there's no need for the version(Tango), unless you plan on supporting phobos too. I'd advise not to do this, as you'll only end up duplicating your efforts, the time's better spent on your actual program :) Plus, should you decide to migrate to D2 at a later date, all these efforts will have been wasted.

Thank you very much :-)
That's the module I was looking for.

Best wishes!
