A C library implementing structured concurrency for writing concurrent programs with deterministic control flow.
libdill is a C library that implements structured concurrency, providing primitives like coroutines and channels to write concurrent programs with clear, deterministic control flow. It solves the problem of managing concurrent operations in C by ensuring all tasks are properly nested and cleaned up, reducing common issues like resource leaks and uncontrolled execution.
C developers building concurrent applications, network servers, or systems requiring lightweight asynchronous operations who need deterministic concurrency management.
Developers choose libdill for its structured approach to concurrency in C, which simplifies reasoning about concurrent code, prevents common pitfalls, and integrates seamlessly with existing C ecosystems without the overhead of traditional threading models.

Ensures all concurrent operations are properly nested and cleaned up, preventing resource leaks and uncontrolled execution, as highlighted in the key features for deterministic control flow.
Provides stackful coroutines for managing asynchronous operations without the complexity of traditional threading, reducing overhead and simplifying code, per the project description.
Implements synchronous channels for communication between coroutines, inspired by Go, making inter-task coordination straightforward and reducing common concurrency bugs.
Includes support for network operations with structured concurrency guarantees, easing development of servers and concurrent network applications, as noted in the key features.
Documentation is hosted on a separate website (libdill.org), which could be inaccessible or less integrated than inline docs, adding a barrier to quick reference.
Adopting structured concurrency demands a mindset change from traditional callback-based or thread-based async patterns, which can slow onboarding for experienced C developers.
As a niche C library, it lacks the extensive tooling, examples, and support found in more popular concurrency frameworks, potentially increasing development time for edge cases.
