From 886a64fe6903bc1ccde5c7af0eac6786918c8e49 Mon Sep 17 00:00:00 2001 From: Zbigniew Jędrzejewski-Szmek Date: Wed, 13 Mar 2013 19:30:05 -0400 Subject: logs-show: export logic to add matches for units After that functions which add matches, show_journal_by_unit and show_journal_by_user_unit, become nearly identical, so I merged them into one function. --- src/shared/logs-show.c | 150 ++++++++++++++++++------------------------------- src/shared/logs-show.h | 19 ++++--- 2 files changed, 66 insertions(+), 103 deletions(-) (limited to 'src/shared') diff --git a/src/shared/logs-show.c b/src/shared/logs-show.c index b909c24e98..43386841ba 100644 --- a/src/shared/logs-show.c +++ b/src/shared/logs-show.c @@ -869,76 +869,68 @@ finish: return r;
