Hi and thanks for your answer. My code looks now like this:

void main(string[] args){
	const(char)* val = "Hello World".std.string.toStringz;
	char* result = write(val);
	const(char)[] s = cstr2dstr(result);
	writeln(s);
	readln(); //keep the window open
}

But now i get the error: "function expected before(), not package 
std of type void" (refering to line 2).

And if i define the variable 'value' as 'const(char)*' i also 
have to rewrite my C-function to accept const(char)*...
