From c02f3f3578f12f950a6beb1bb11e7853698f0499 Mon Sep 17 00:00:00 2001 From: poljar Date: Wed, 28 Mar 2012 21:18:54 +0200 Subject: [PATCH] Added --help and --version options for pacmd All utilities should have the --help and --version command line options. These two were added to pacmd, also the goto label was changed from fail to quit like in the other utilities. --- src/utils/pacmd.c | 100 ++++++++++++++++++++++++++++++++++++++++++++++------- 1 file changed, 88 insertions(+), 12 deletions(-) diff --git a/src/utils/pacmd.c b/src/utils/pacmd.c index 28411d3..99553bd 100644 --- a/src/utils/pacmd.c +++ b/src/utils/pacmd.c @@ -30,6 +30,7 @@ #include #include #include +#include #include #include @@ -42,6 +43,51 @@ #include #include +static void help(const char *argv0) { + printf("%s %s\n", argv0, "exit");
