From f663924517e9380f74c2e821ff29f973705e8654 Mon Sep 17 00:00:00 2001 From: Richard Mudgett Date: Mon, 23 Apr 2012 17:05:55 +0000 Subject: Make app_dial and app_queue use new macro and gosub calls. * Simplify some code in app_dial and app_queue by calling ast_app_exec_macro() and ast_app_exec_sub(). * Fix minor locking issue in app_dial for post-answer macro/gosub MACRO/GOSUB_RESULT=GOTO: handling. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@363269 65c4cc65-6c06-0410-ace0-fbb531ad65f3 --- apps/app_dial.c | 176 +++++++++++++++++++------------------------------------- 1 file changed, 60 insertions(+), 116 deletions(-) (limited to 'apps/app_dial.c') diff --git a/apps/app_dial.c b/apps/app_dial.c index 76f3bf36e..875e943e3 100644 --- a/apps/app_dial.c +++ b/apps/app_dial.c @@ -2626,40 +2626,26 @@ static int dial_exec_full(struct ast_channel *chan, const char *data, struct ast } if (ast_test_flag64(&opts, OPT_CALLEE_MACRO) && !ast_strlen_zero(opt_args[OPT_ARG_CALLEE_MACRO])) { - struct ast_app *theapp;
