From 9dc09c766463333ca51311a2db86fd67f4fec19b Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Mon, 12 Mar 2007 14:37:28 -0400 Subject: [PATCH] Simplify closing two fds at once in run-command.c I started hacking on a change to add stdout redirection support to the run_command family, but found I was using a lot of close calls on two pipes in an array (such as for pipe). So I'm doing a tiny bit of refactoring first to make the next set of changes clearer. Signed-off-by: Shawn O.
