From e4bff8be94c0db4f94e63ad448d0eeb869ccdbbd Mon Sep 17 00:00:00 2001 From: ShadowNinja Date: Tue, 7 Apr 2015 06:13:12 -0400 Subject: Clean up threading * Rename everything. * Strip J prefix. * Change UpperCamelCase functions to lowerCamelCase. * Remove global (!) semaphore count mutex on OSX. * Remove semaphore count getter (unused, unsafe, depended on internal API functions on Windows, and used a hack on OSX). * Add `Atomic`. * Make `Thread` handle thread names. * Add support for C++11 multi-threading. * Combine pthread and win32 sources. * Remove `ThreadStarted` (unused, unneeded). * Move some includes from the headers to the sources. * Move all of `Event` into its header (allows inlining with no new includes). * Make `Event` use `Semaphore` (except on Windows). * Move some porting functions into `Thread`. * Integrate logging with `Thread`. * Add threading test. --- src/threading/thread.h | 119 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 119 insertions(+) create mode 100644 src/threading/thread.h (limited to 'src/threading/thread.h') diff --git a/src/threading/thread.h b/src/threading/thread.h new file mode 100644 index 000000000..275bc9b6d --- /dev/null +++ b/src/threading/thread.h @@ -0,0 +1,119 @@ +/* +This file is a part of the JThread package, which contains some object- +oriented thread wrappers for different thread implementations. + +Copyright (c) 2000-2006 Jori Liesenborgs (jori.liesenborgs@gmail.com) + +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.
