From db6d60b30a5d18ee12e0565a026b09b7dd7651bf Mon Sep 17 00:00:00 2001 From: Andreas Schwab Date: Tue, 21 Oct 2014 12:58:27 +0200 Subject: [PATCH] prctl.2: Correct description of null-termination in PR_GET_NAME and PR_SET_NAME The size of the process name has always been at most 16 byte _including_ the null terminator. This also means that the name returned by PR_GET_NAME is always null-terminated.
