From 5efb9fbd5f1bfe4435bd0a3ea5f0e187875509c2 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Fri, 1 Nov 2013 17:53:58 -0400 Subject: [PATCH] tools lib traceevent: Check for spaces in character array Currently when using the raw format for fields, when looking at a character array, to determine if it is a string or not, we make sure all characters are "isprint()". If not, then we consider it a numeric array, and print the hex numbers of the characters instead. But it seems that '\n' fails the isprint() check! Add isspace() to the check as well, such that if all characters pass isprint() or isspace() it will assume the character array is a string.
