Platform-dependent.

For Windows, you can use the concatenation of HOMEDRIVE and HOMEPATH, but I 
don't know under which versions of Windows these variables are actually set.

----------
import std.c.stdlib, std.string, std.stdio;

void main() {
    string homeDrive, homePath;
    homeDrive = toString(getenv("HOMEDRIVE")).dup;
    homePath = toString(getenv("HOMEPATH")).dup;

    writefln("%s%s", homeDrive, homePath);
}
----------

For Unix, I'm informed that the HOME environment variable does it.
