Pin is a basic, simple component technology suitable for building embedded software applications. Pin implements the container idiom for software components. Containers provide a prefabricated “shell” in which custom code executes and through which all interactions between custom code and its external environment are mediated. Pin is a component technology for pure assembly—systems are assembled by selecting components and connecting their interfaces (which are composed of communication channels called pins).

This report describes the main concepts of Pin and documents the C-language interface to Pin V1.0.
