Shared Memory

Shared memory interfaces are only available with the NuttX kernel build (CONFIG_BUILD_KERNEL=y). These interfaces support user memory regions that can be shared between multiple user processes. The user interfaces are provided in the standard header file include/sys/shm.h>. All logic to support shared memory is implemented within the NuttX kernel with the exception of two low-level functions that are require to configure the platform-specific MMU resources. Those interfaces are described below:
