From 3cc7978f19f55a4f3ff7209d67bbb1b0ccb7c4ff Mon Sep 17 00:00:00 2001 From: Sergey Sharybin Date: Mon, 23 Dec 2013 22:48:20 +0600 Subject: Move python threading stuff to own file in bf_python_ext This way blender player can easily use BPY_thread_save/restore. Not so much important for master branch, but crucial to solve linking issues in threaded depsgraph branch. --- source/blender/python/generic/bpy_threads.c | 67 +++++++++++++++++++++++++++++ 1 file changed, 67 insertions(+) create mode 100644 source/blender/python/generic/bpy_threads.c (limited to 'source/blender/python/generic/bpy_threads.c') diff --git a/source/blender/python/generic/bpy_threads.c b/source/blender/python/generic/bpy_threads.c new file mode 100644 index 00000000000..610c1846f56 --- /dev/null +++ b/source/blender/python/generic/bpy_threads.c @@ -0,0 +1,67 @@ +/* + * ***** BEGIN GPL LICENSE BLOCK ***** + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License + * as published by the Free Software Foundation; either version 2 + * of the License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
