Provides a thread-safe, context-aware logging system with severity levels and automatic timestamping. Implements a clean API for logging with minimal overhead, supporting both synchronous and asynchronous modes. Can be extracted as a standalone logging library for any C application requiring robust diagnostics.

Wrappers for malloc/free that track allocations, provide aligned allocation options, and log errors on failure. Includes functions for zero-filled allocation and memory reuse pools. Reduces boilerplate for error checking in memory management while adding diagnostic capabilities. Suitable for extraction into any C project needing safer memory handling.

Implements robust synchronization primitives (mutexes, condition variables, semaphores) with error-checking and initialization safety. Features include adaptive mutexes, robust condition variables, and semaphores with timeout support. Avoids common pitfalls like forgetting to initialize or destroy locks. Can be used in multi-threaded C applications requiring reliable synchronization.

Offers nanosecond-resolution time operations, monotonic clocks, and timer utilities. Provides a consistent interface for time measurements across systems, including functions for elapsed time calculation and deadline handling. Simplifies time-based logic in performance-critical code. Easily portable to other projects needing precise timing.

Defines a hierarchical error code system with base offsets for subsystems, automatic errno translation, and error registration/lookup mechanisms. Enables consistent error reporting across large codebases while maintaining compatibility with standard error codes. Includes utilities for error string lookup and error propagation. Valuable for any C project requiring structured error handling.
