From c83642c69ede418f4c4d89daa0dae4b8698e0765 Mon Sep 17 00:00:00 2001 From: Kazumasa Mitsunari Date: Mon, 19 Mar 2018 17:06:05 +0900 Subject: Change reply timing Some events were emitted in a function before it replies. This patch changes * The function checks parameter then reply error if it is incorrect. * After checking parameters, the function continues to process. The exeption is the syncronous functions such as requestSurface.
