Note

CGreenlet doesn't use the "stack splicing" approach that other green threads implementations use. This means that a whole stack will be allocated per greenlet. This is a lot less memory effcient than using stack splicing.

You should consider this code mostly as a proof of concept. For a proven real-world implementation of green threads with stack splicing see the "stacklet" implementatin from PyPy:

https://bitbucket.org/pypy/pypy/src/default/rpython/translator/c/src/stacklet

The Stacklet API is a little bit more low-level. Stacklet would be an ideal backend for CGreenlet.

Overview

CGreenlet is a FAST! and cross-platfrm coroutine library for C/C++. The API is modeled after the Python "greenlet" API [1]_.
