Low-Latency Market Data Ring Buffer (IPC) - Quant Developer Interview Question

Problem Description

In high-frequency trading, distributing market data from feed handlers to strategy engines with minimal latency is critical for execution performance. Inter-Process Communication (IPC) via shared memory eliminates kernel socket overhead, providing a highly efficient mechanism for data transfer between distinct processes. This problem involves implementing a lock-free ring buffer using POSIX shared memory primitives to achieve low-latency message passing. Task Implement a class SharedMemoryQueue
