portview C++ / Windows SDK
01. System Overview & One-Liner
Windows CLI tool to list open ports, map them to processes, and display per-connection traffic stats — built with C++ and Windows SDK.
02. Key Engineering Capabilities
- ▹ Live Socket Enumeration: Queries TCP/UDP connection tables directly using Windows IP Helper API (
IPHLPAPI). - ▹ PID Process Mapping: Resolves owner Process IDs to active process executable paths in real time.
- ▹ Traffic Inspection & Stats: Tracks per-connection byte transfer rates and connection states.
- ▹ Zero External Dependencies: Native C++ binary compiled directly against the Windows SDK.
