=============

C++ Green threads and coroutines library

**Motivation:**
* 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](https://github.com/yigalirani/green_threads/blob/master/green_threads.h) and [example program](https://github.com/yigalirani/green_threads/blob/master/green_threads_test.cpp)

**Future development:**
* Integrate the library with IO functionality like sockets and files
* Further improve speed .
* Add dynamic number of green threads.
* Port to non msvc/windows compilers and operating systems.
* Port to non-x86 processors such as arm.

**How does it work:**

The library explicitly allocate runtime stack for each green thread.  The gt_yield function switches the current green thread by manipulating, using assembler, the esp and ebp registers who point the current runtime stack.
