For - example, some functions and features, such as those based - on POSIX signals, are missing. - - Pthreads-win32 is a library, available in several different - versions depending on supported compilers, and may be used - as a dynamically linked module or a statically linked set of - binary modules. It is not an application on it's own. - - It was fully intended that pthreads-win32 be usable with - commercial software not covered by either the GPL or the LGPL - licenses. Pthreads-win32 has many contributors to it's - code base, many of whom have done so because they have - used the library in commercial or proprietry software - projects. - - Releasing pthreads-win32 under the LGPL ensures that the - library can be used widely, while at the same time ensures - that bug fixes and improvements to the pthreads-win32 code - itself is returned to benefit all current and future users - of the library. - - Although pthreads-win32 makes it possible for applications - that use POSIX threads to be ported to Win32 platforms, the - broader goal of the project is to encourage the use of open - standards, and in particular, to make it just a little easier - for developers writing Win32 applications to consider - widening the potential market for their products. diff --git a/src/external/pthread/include/pthread.h b/src/external/pthread/include/pthread.h deleted file mode 100644 index b4072f72..00000000 --- a/src/external/pthread/include/pthread.h +++ /dev/null @@ -1,1368 +0,0 @@ -/* This is an implementation of the threads API of POSIX 1003.1-2001. - * - * -------------------------------------------------------------------------- - * - * Pthreads-win32 - POSIX Threads Library for Win32 - * Copyright(C) 1998 John E.

My - assumption is that almost nobody was doing this, and those who - were will find the built-in SIMD more satisfactory anyway. - - - RGB values computed for JPEG images are slightly different from - previous versions of stb_image. (This is due to using less - integer precision in SIMD.) The C code has been adjusted so - that the same RGB values will be computed regardless of whether - SIMD support is available, so your app should always produce - consistent results. But these results are slightly different from - previous versions. (Specifically, about 3% of available YCbCr values - will compute different RGB results from pre-1.49 versions by +-1; - most of the deviating values are one smaller in the G channel.) - - - If you must produce consistent results with previous versions of - stb_image, #define STBI_JPEG_OLD and you will get the same results - you used to; however, you will not get the SIMD speedups for - the YCbCr-to-RGB conversion step (although you should still see - significant JPEG speedup from the other changes). - - Please note that STBI_JPEG_OLD is a temporary feature; it will be - removed in future versions of the library. It is only intended for - near-term back-compatibility use. - - - Latest revision history: +LICENSE + + See end of file for license information. + +RECENT REVISION HISTORY: + + 2.15 (2017-03-18) fix png-1,2,4; all Imagenet JPGs; no runtime SSE detection on GCC + 2.14 (2017-03-03) remove deprecated STBI_JPEG_OLD; fixes for Imagenet JPGs 2.13 (2016-12-04) experimental 16-bit API, only for PNG so far; fixes 2.12 (2016-04-02) fix typo in 2.11 PSD fix that caused crashes 2.11 (2016-04-02) 16-bit PNGS; enable SSE2 in non-gcc x64 RGB-format JPEG; remove white matting in PSD; - allocate large structures on the stack; + allocate large structures on the stack; correct channel count for PNG & BMP 2.10 (2016-01-22) avoid warning introduced in 2.09 2.09 (2016-01-16) 16-bit TGA; comments in PNM files; STBI_REALLOC_SIZED @@ -174,32 +78,26 @@ Ken Miller (pgm, ppm) Richard Mitton (16-bit PSD) github:urraka (animated gif) Junggon Kim (PNM comments) Daniel Gibson (16-bit TGA) - socks-the-fox (16-bit TGA) + socks-the-fox (16-bit PNG) + Jeremy Sawicki (handle all ImageNet JPGs) Optimizations & bugfixes Fabian "ryg" Giesen Arseny Kapoulkine Bug & warning fixes Marc LeBlanc David Woo Guillaume George Martins Mozeiko - Christpher Lloyd Martin Golini Jerry Jansson Joseph Thomson - Dave Moore Roy Eltham Hayaki Saito Phil Jordan - Won Chun Luke Graham Johan Duparc Nathan Reed - the Horde3D community Thomas Ruf Ronny Chevalier Nick Verigakis - Janez Zemva John Bartholomew Michal Cichon github:svdijk - Jonathan Blow Ken Hamada Tero Hanninen Baldur Karlsson - Laurent Gomila Cort Stratton Sergio Gonzalez github:romigrou - Aruelien Pocheville Thibault Reuille Cass Everitt Matthew Gregan - Ryamond Barbiero Paul Du Bois Engin Manap github:snagar - Michaelangel007@github Oriol Ferrer Mesia Dale Weiler github:Zelex - Philipp Wiesemann Josh Tobin github:rlyeh github:grim210@github - Blazej Dariusz Roszkowski github:sammyhw - - -LICENSE - -This software is dual-licensed to the public domain and under the following -license: you are granted a perpetual, irrevocable license to copy, modify, -publish, and distribute this file as you see fit. + Christpher Lloyd Jerry Jansson Joseph Thomson Phil Jordan + Dave Moore Roy Eltham Hayaki Saito Nathan Reed + Won Chun Luke Graham Johan Duparc Nick Verigakis + the Horde3D community Thomas Ruf Ronny Chevalier Baldur Karlsson + Janez Zemva John Bartholomew Michal Cichon github:rlyeh + Jonathan Blow Ken Hamada Tero Hanninen github:romigrou + Laurent Gomila Cort Stratton Sergio Gonzalez github:svdijk + Aruelien Pocheville Thibault Reuille Cass Everitt github:snagar + Ryamond Barbiero Paul Du Bois Engin Manap github:Zelex + Michaelangel007@github Philipp Wiesemann Dale Weiler github:grim210 + Oriol Ferrer Mesia Josh Tobin Matthew Gregan github:sammyhw + Blazej Dariusz Roszkowski Gregory Mullen github:phprus */ @@ -274,13 +172,13 @@ publish, and distribute this file as you see fit. // and for best performance I may provide less-easy-to-use APIs that give higher // performance, in addition to the easy to use ones.

* by the Activity's main thread when certain events occur. - * - * This means that each one of this callbacks _should_ _not_ block, or they - * risk having the system force-close the application. This programming - * model is direct, lightweight, but constraining. - * - * The 'threaded_native_app' static library is used to provide a different - * execution model where the application can implement its own main event - * loop in a different thread instead. Here's how it works: - * - * 1/ The application must provide a function named "android_main()" that - * will be called when the activity is created, in a new thread that is - * distinct from the activity's main thread. - * - * 2/ android_main() receives a pointer to a valid "android_app" structure - * that contains references to other important objects, e.g. the - * ANativeActivity obejct instance the application is running in. - * - * 3/ the "android_app" object holds an ALooper instance that already - * listens to two important things: - * - * - activity lifecycle events (e.g. "pause", "resume"). See APP_CMD_XXX - * declarations below. - * - * - input events coming from the AInputQueue attached to the activity. - * - * Each of these correspond to an ALooper identifier returned by - * ALooper_pollOnce with values of LOOPER_ID_MAIN and LOOPER_ID_INPUT, - * respectively. - * - * Your application can use the same ALooper to listen to additional - * file-descriptors. They can either be callback based, or with return - * identifiers starting with LOOPER_ID_USER. - * - * 4/ Whenever you receive a LOOPER_ID_MAIN or LOOPER_ID_INPUT event, - * the returned data will point to an android_poll_source structure. You - * can call the process() function on it, and fill in android_app->onAppCmd - * and android_app->onInputEvent to be called for your own processing - * of the event. - * - * Alternatively, you can call the low-level functions to read and process - * the data directly... look at the process_cmd() and process_input() - * implementations in the glue to see how to do this. - * - * See the sample named "native-activity" that comes with the NDK with a - * full usage example.
