I don't follow.

You have two functions, pthread_attr_setperthreadfs_np, and
pthread_attr_setperthreadids_np.

You want to call them with the permutation of their options
and check the results.

At an API level the arguments used to call them are unrelated.

I don't understand what you what to express in the last paragraph.
