The Portable Operating System Interface (POSIX) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems. FreeRTOS+POSIX implements a subset of the POSIX threading API.
With FreeRTOS+POSIX, an existing POSIX threading compliant application can be ported to run on the FreeRTOS kernel, and therefor leverage all the Amazon FreeRTOS functionality. Additionally, a library designed for use with POSIX threading compatible operating systems can be ported to FreeRTOS kernel based applications.

The demo project is located under FreeRTOS-Plus\Demo\FreeRTOS_Plus_POSIX_with_actor_Windows_Simulator.
