From 057c15b5495d61a14b948b203c0d68b03b7988c7 Mon Sep 17 00:00:00 2001 From: Sergey Sharybin Date: Fri, 27 Nov 2020 15:58:55 +0100 Subject: Libmv: Add threading primitives Allows to use mutex, scoped_lock, and conditional_variable from within the libmv namespace. Implementation is coming from C++11. Other configurations are easy to implement, but currently C++11 is the way to go. --- intern/libmv/libmv/threading/threading.h | 43 ++++++++++++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100644 intern/libmv/libmv/threading/threading.h (limited to 'intern') diff --git a/intern/libmv/libmv/threading/threading.h b/intern/libmv/libmv/threading/threading.h new file mode 100644 index 00000000000..f23bf6f172c --- /dev/null +++ b/intern/libmv/libmv/threading/threading.h @@ -0,0 +1,43 @@ +// Copyright (c) 2020 libmv authors. +// +// Permission is hereby granted, free of charge, to any person obtaining a copy +// of this software and associated documentation files (the "Software"), to +// deal in the Software without restriction, including without limitation the +// rights to use, copy, modify, merge, publish, distribute, sublicense, and/or +// sell copies of the Software, and to permit persons to whom the Software is +// furnished to do so, subject to the following conditions: +// +// The above copyright notice and this permission notice shall be included in +// all copies or substantial portions of the Software. +// +// THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +// IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +// FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
