Detailed Description

One process (space) record in the shared process table.

The four *QID fields index into ProcessMemoryStruct::qIndex to locate this process's command/message/signal/request queues within the segment.

Warning

Shared-memory layout; see MemoryManager.h for the ABI/rebuild warning.
