Yes, it would; but so would `system'.  They both do the same, so the
above two commands will work (or fail ;-) in the same way.

This is correct.  I cannot imagine why would anyone want to launch a
child program just to list a directory anyway, but here you are, take 2:

	FILE *fp = popen ("command.com /c dir *.exe /s", "rt");
	fread (fp, ...);

An excercise that is left to the interested reader: why did I say
"command.com" and not simply "command"?
