Golang supports native thread and multi process?

If I don't want to use goroutine.

There is no direct access to native threads in Go.

Go does support multiple processes via the os/exec package.

what exactly are you trying to do? why do you think you need pthreads to do it?

[小菜]

Let goroutine run in the specified CPU core

Get goroutine ID

Let the appointed tasks running on the specified goroutine

Because  I can't do this , it is  not suported!

So  I want to use natvie thread or multi process.

depending on why you want this you can simulate it in any number of
ways. for example, you can assign each goroutine a unique id on
startup. this is independent of the runtime.

you can do this by sending the appropriate task to the appropriate
goroutine. function pointers are first class members in Go's type
system. this is a communications problem, not a language problem.

I recommend using Go as it is designed to be used.

If you want pthreads, use C or C++.

Definitely.

In C++11 and later you do not use pthreads. If you use threads, you
use std::thread. Actually in modern C++ you shouldn't really be
explicitly using threads, you should do things with asynchronous
function calls and futures.
