Yes, skip the temporary, that is what pipes are for. (See popen(3), as
ObOtherPoster already pointed out.)

AFAIK, ps(1) is system-dependent; there is _no_ portable way to get to
that data other than to read ps output. That is, a ps from NetBSD will
not necessairily work (or even compile) on solaris, for example.
(Also: There is no such language as ``C/C++''.)
