What if you enter that command in a subshell? What if it isn't a shell at
all?
Apart form these problems, there is no way to find the cwd of another
process on unix in general, even if you *knew* the process.
The right solution is to teach your shell to tell urxvt about the cwd and
use that in your extension (for example, by setting an x-property via a
command sequence and querying that before opening a window).

Of course, the cwd of urxvtc is /home/muresan.

Yes, the cwd of urxvtc in that case is /. urxvtc sends the cwd to urxvtd.

/ is simply the cwd of urxvtd, so when you start urxvtc from within
urxvtd, it will use that as cwd.

Yes, but it works just as well within urxvt, both support multiple
terminal windows from a single process.

Yes, it might be a good idea to put this into the default popups as well,
actually.
