Local continuations
+ +[Protothreads] +

Detailed Description

+Local continuations form the basis for implementing protothreads. +

+A local continuation can be set in a specific function to capture the state of the function. After a local continuation has been set can be resumed in order to restore the state of the function at the point where the local continuation was set. +
