PT_SCHEDULE() now returns true both when a protothread is waiting and when it has yielded. A README file has been added for Visual C++ users that explains how protothreads may trigger a compiler bug and how to prevent this from happening.
It is now possible to determine if a protothread
is waiting, or has yielded, exited, or ended by
looking at the return value of a protothread
function.
A missing parenthesis in the implementation of
PT_SCHEDULE() that could cause problems has been
fixed. The PT_YIELDING() macro is no longer needed
inside a protothread that yields.
This release adds PT_YIELD() functionality that allows a protothread to
yield the CPU. PT_SPAWN() now properly takes two pt state structures as
parameters. The examples should compile under MS Windows.
