Greeny is a C++ Green threads and coroutines library

This is a complete rewrite of https://github.com/yigalirani/green_threads library.

Advantages over original library

• Multiple platforms are supported. Original library was hardly bound to MS VisualStudio on i386.
• Fully object-oriented design with no global variables - this allows using green threads in multithreaded programs. You may have multiple green thread sets (contexts) in multiple threads.
• Arbitrary callback types (functors, callable objects, etc.)
• Variable stack sizes - you may set allocated stack size for each green thread.
• next() function without "tid" parameter to get a posted value of any other thread.

Motivation (same as in original library):

• Write faster multithreaded programs by utilizing reduced context switch time.
• Write shorter and more elegant programs by using the yield functionality that is modeled after the python yield keyword and co-routines.

Getting started: look at the very short api and example program

Future development:

• Automatically grow stack sizes if stacks are nearly exhausted

Requirements

• C++11-compatible compiler
• boost libraries (Used: ptr_containers)

Building Build test using CMake:

• mkdir build
• cd build
• cmake -DCMAKE_BUILD_TYPE=DEBUG ..
• make

Platforms

• GCC on AMD64
• GCC on i386
