From aa1aac17a15cbf64236bd6f3b855262dcfb845c9 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 3 Feb 2015 12:46:58 -0300 Subject: [PATCH] perf tools: Introduce event_format__fprintf method The existing one, event_format__print() uses stdout unconditionally, and 'perf trace' needs to use it to format into a file that may have been set by the user, i.e. 'trace -o file.output'.
