From c31982b09dda5aa556455e13ee5aa1adf66e9da4 Mon Sep 17 00:00:00 2001 From: Andre Noll Date: Wed, 27 Jun 2012 22:32:16 +0200 Subject: [PATCH] Interactive: Introduce i9e_get_error(). Currently there is no easy way for a paraslash task to find out whether the i9e task is still up and running. This commit adds the new public function i9e_get_error() which simply returns the error state of the i9e task. --- interactive.c | 14 ++++++++++++++ interactive.h | 1 + 2 files changed, 15 insertions(+) diff --git a/interactive.c b/interactive.c index 7768d36b..cd5fa8a8 100644 --- a/interactive.c +++ b/interactive.c @@ -38,6 +38,20 @@ struct i9e_private { }; static struct i9e_private i9e_private, *i9ep = &i9e_private; +/** + * Return the error state of the i9e task. + * + * This is mainly useful for other tasks to tell whether the i9e task is still + * running. + * + * \return A negative return value of zero means the i9e task terminated.
