In C# you can do that:

var file = new Uri(filename).AbsoluteUri;
// file is "file:///C:/path/to/my/file.txt"
How can I do that in D?

are shared between the threads. So, calling not pure functions

The documentation says:
Important Note: When passing a char* to a C function, and the C
function keeps it around for any reason, make sure that you keep
a reference to it in your D code. Otherwise, it may become
invalid during a garbage collection cycle and cause a nasty bug
