Popen;

You will need to do something like:

extern(C) FILE *popen(const char *command, const char *mode);

in your D source file before you can call it.  See dm\include\stdio.h 
for the function declaration.  Any function you can find in the dm 
include directories can be called like this.

I wrote a ProcessStream using CreateProcess etc which worked on both 
windows and linux (although there may have been a few bugs to deal with):
