From 6f9a317f2a2d4950880ecfa7eea53ed79f85255f Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Thu, 28 Nov 2013 11:30:17 +0100 Subject: [PATCH] perf tools: Add perf_data_file__write interface Adding perf_data_file__write interface to centralize output to files. The function prototype is: ssize_t perf_data_file__write(struct perf_data_file *file, void *buf, size_t size); Returns number of bytes written or -1 in case of error. NOTE: Also indenting 'struct perf_data_file' members, no functional change done.
