From e9a9bad264daf22604dc1e51c81d6dcfd8550736 Mon Sep 17 00:00:00 2001 From: Jim Warner Date: Fri, 13 Apr 2012 13:13:13 -0500 Subject: [PATCH] top: document an existing provision of pid monitoring Since its inception top has provided for monitoring only specific process ids via the -p command line switch. This provision has also embraced the top process itself, even though its pid wasn't yet known. This commit simply documents the special zero value, which would otherwise be an invalid process id.
