Binary Protocol C++ Example

A minimal, professional, byte-level binary protocol implementation in C++.

Features

• Fixed-layout wire format (24 bytes)
• Explicit endianness, alignment, and validation
• XOR checksum for payload integrity

Usage

• make test — run unit tests
• make visual — see byte-level visualization

Wire Format

[2] msg_type | [2] msg_len | [2] checksum | [8] order_id | [4] price | [4] quantity | [1] side | [1] padding
