Detailed Description

Lockless shared memory byte stream IPC.

The sys_winstream utility implements a unidirectional byte stream with simple read/write semantics on top of a memory region shared by the writer and reader. It requires no locking or synchronization mechanisms beyond reliable ordering of memory operations, and so is a good fit for use with heterogenous shared memory environments (for example, where Zephyr needs to talk to other CPUs in the system running their own software).
