CPU release when waiting data through thread

[Andrea Verdecchia]

A simple and maybe trivial question. When in a thread I wait data for example with

k_pipe_get( &pipe, &buffer, size, &bytesRead, totalSize, K_FOREVER );

is it like call continuously the k_yield()? How the api above works in the underhood?

Hi!

Yes, AFAIK the function will then suspend the calling thread.

You can check what threads are running, and suspended, etc. with the Thread Viewer.
