Calling k_thread_create with K_FOREVER timeout and never starting it

[adrdub]

Hello,

I couldn't find the answer in Zephyr's docs for following aspect: is it safe to call k_thread_create function with K_FOREVER timeout multiple times and never starting created threads? I see no API to for eg. cancel such 'non-started' thread, however its ID is already known. Or maybe k_thread_abort should be called? What'd be recommended for such use case?

BR,
Adrian

I don't know what is the definition of safe for you. But your system should work without those threads, given that each k_thread_create() is given a unique set of arguments.

To remove a thread from the Kernel, you should call k_thread_abort(), then free all resources it had. Just grep through the source code and you'll see many usage of k_thread_abort().

That was my guess, however I didn't find clear statement in docs for this specific use case. Thanks!
