IPC (Local)

Local IPC

Designed for ultra-low latency communication between local applications (e.g., Canvas and Paint).

SharedMemoryConnection

• Use Case: High-frequency data (e.g., continuous property updates, large texture uploads).
• Mechanism: Ring buffers in memory-mapped files.
• Performance: Zero-copy (writes directly to shared region).
• Synchronization: Platform-specific (Futex on Linux, Ulock on macOS).
• Architecture: Similar to Wayland’s wl_shm.

UnixSocketConnection (macOS/Linux)

• Use Case: Reliable command channel, control messages.
• Mechanism: AF_UNIX domain sockets.
• Features: Ordered delivery, FD passing (future), widely supported.

NamedPipeConnection (Windows)

• Use Case: Windows equivalent of Unix Sockets.
• Mechanism: Windows Named Pipes (CreateNamedPipe).
• Features: Overlapped I/O for async operations.
