From df43c2d38047a6dd625e20b97ca6efb4fb0120a3 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Wed, 20 Jul 2016 18:58:52 +0900 Subject: ctl: use condition statements instead of assert() for new APIs to add an element set Usage of assert() is not better practice of programming as shared library APIs. They should return appropriate error code to promote applications to handle error state. This commit applies condition statements with return value of -EINVAL, instead of assert(). As a backward compatibility for existent applications, old APIs still call assert().
