C语言中的Go风格频道

Question

For a real time DSP program in C, I need something like Go-style channels to communicate between threads:

• One thread pushes tokens on the channel
• Another thread pulls tokens from the channel
• The channel has a buffer
• In my case, tokens have a small memory footprint (small vectors of numbers)

I was wondering if using good old streams was a good idea, or not. If not, is there a good practice and/or a library to get something as close as Go channels as possible?

What you're describing describes a thread-safe queue.

The Apache Project has one implementation.

Other than that, a lot of users have actually shared their pthread queue implementations, assuming that was what you're using.
