Detailed Description

Client-side endpoint of the named shared-memory request/reply service.

A MemoryRequestServer creates a named segment with a RequestServerHeader, a request- status table and per-connection queue areas. Any process connects by name with a MemoryRequestConnection, then either issues requests (makeRequest/waitForRequestReply) or serves them (waitForRequest/replyToRequest). Replies that arrive out of order are held in a local replyCache keyed by request id.

Warning

Shared-memory layouts; changing any struct here requires a full rebuild of all binaries (make clean && make) — see MemoryManager.h for the ABI warning.
