Using C function in Tango - Simple solution?

[Fabian Classen]

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.
