Question 1

How does Neco compare to libcoroutine?

Accepted Answer

Neco offers a higher-level API with channels and generators similar to Go, while libcoroutine is more low-level. Neco is single-file and has better Posix integration, but libcoroutine might be more flexible for custom implementations.

Question 2

Can Neco be used with multithreading?

Accepted Answer

Neco uses thread-local runtimes, so each thread has its own scheduler. Communication between threads requires I/O mechanisms like pipes, as pthread synchronization doesn't work well, limiting true parallel execution.

Question 3

How to handle blocking I/O in Neco coroutines?

Accepted Answer

On Linux and BSD, use neco_wait() to poll file descriptors without blocking. Otherwise, rely on cooperative multitasking with neco_sleep() and other primitives, but avoid traditional blocking calls that stall the scheduler.

Question 4

Is Neco good for embedded systems?

Accepted Answer

Yes, due to its small footprint and no dependencies, but be cautious of default stack sizes (e.g., 1MB on Windows/WebAssembly) and platform limitations on resource-constrained devices.

Question 5

Neco or asyncio for C projects?

Accepted Answer

Neco provides coroutines with a Go-like model, ideal for single-threaded concurrency with simple APIs. Asyncio or other libraries might be better for event-driven architectures or if you need multithreading support.

Question 6

How to create a TCP server with Neco?

Accepted Answer

Use neco_serve() to bind and listen on an address, then neco_accept() in a loop to handle connections, starting coroutines with neco_start() for each client, as shown in the echo server example.

Question 7

What are the memory usage considerations for Neco?

Accepted Answer

Each coroutine has a stack; default sizes vary by platform (e.g., larger on Linux/BSD, 1MB on Windows/WebAssembly). Guards and gaps are not supported on all platforms, so monitor stack overflow risks in heavy workloads.
