What problem does it solve?

This Skill provides expert assistance for complex POSIX real-time and systems programming challenges, ensuring deterministic behavior and high performance in C/C++ applications.

Core Features & Use Cases

• Concurrency Control: Expert guidance on pthreads, mutexes, condition variables, and semaphores with priority inheritance.
• Scheduling & Timing: Deep dives into POSIX timers, scheduling policies (FIFO, RR, DEADLINE), and clock management.
• Use Case: Debugging a hard real-time control loop that is experiencing jitter; optimizing process scheduling for minimal latency; implementing high-performance inter-process communication using POSIX message queues or shared memory.

Quick Start

Explain how to use CLOCK_MONOTONIC for all real-time interval timing.
