I think I've noticed one problem with the code above. You are using `text.ptr`. You shouldn't do that because you are passing a pointer not an array. Just use `text`.

Forget this line, my mistake. Use `toStringz` and pass a pointer instead of an array.

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)*...

Use an import.

import std.string;
import std.conv;

void main(string[] args) {
    auto value  = toStringz("Hello World");
    auto result = write(value);
    auto s      = to!(string)(result);
    writeln(s);
}

Also all string literals in D are zero terminated so you could write the call like this:

auto result = write("Hello World");
