Userspace API

Note

Migration in progress

This manual provides general usage information for the NuttX RTOS from the perspective of the firmware developer.

The intended audience for this document are firmware developers who are implementing applications on NuttX. Specifically, this documented is limited to addressing only NuttX RTOS APIs that are available to the application developer. As such, this document does not focus on any technical details of the organization or implementation of NuttX. Those technical details are provided in the NuttX Porting Guide.

Information about configuring and building NuttX is also needed by the application developer. That information can also be found in the NuttX Porting Guide.
