From 7d0b18a4da1be9e738293cc13812757ca47ed109 Mon Sep 17 00:00:00 2001 From: Anders Melchiorsen Date: Mon, 4 Aug 2008 12:18:40 +0200 Subject: [PATCH] Add output flushing before fork() This adds fflush(NULL) before fork() in start_command(), to keep the generic interface safe. A remaining use of fork() with no flushing is in a comment in show_tree(). Rewrite that comment to use start_command().
