From a86c1d68e9e2025847cacceaded3941fa099c9d6 Mon Sep 17 00:00:00 2001 From: David Vossel Date: Fri, 8 Jul 2011 20:18:39 +0000 Subject: Moves celt and silk format attribute files into res folder. It was inconsistent to have the silk and celt format attribute modules in the format file interpreter folder. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@327116 65c4cc65-6c06-0410-ace0-fbb531ad65f3 --- formats/format_attr_celt.c | 181 -------------------------------------- formats/format_attr_silk.c | 215 --------------------------------------------- res/res_format_attr_celt.c | 181 ++++++++++++++++++++++++++++++++++++++ res/res_format_attr_silk.c | 215 +++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 396 insertions(+), 396 deletions(-) delete mode 100644 formats/format_attr_celt.c delete mode 100644 formats/format_attr_silk.c create mode 100644 res/res_format_attr_celt.c create mode 100644 res/res_format_attr_silk.c diff --git a/formats/format_attr_celt.c b/formats/format_attr_celt.c deleted file mode 100644 index de3de8c40..000000000 --- a/formats/format_attr_celt.c +++ /dev/null @@ -1,181 +0,0 @@ -/* - * Asterisk -- An open source telephony toolkit. - * - * Copyright (C) 2011, Digium, Inc. - * - * David Vossel - * - * See http://www.asterisk.org for more information about - * the Asterisk project.
