From c58dbf28e06b68a852028663b342eca98e739ab5 Mon Sep 17 00:00:00 2001 From: Bernhard Reutner-Fischer Date: Tue, 30 May 2006 12:16:54 +0000 Subject: - remove useless variable "status" from init_main. http://www.opengroup.org/onlinepubs/009695399/functions/waitpid.html suggests that we need not specify a status if we don't want, and we don't. "If wait() or waitpid() return because the status of a child process is available, these functions shall return a value equal to the process ID of the child process. In this case, if the value of the argument stat_loc is not a null pointer, information shall be stored in the location pointed to by stat_loc.
