Yes it is documented and one can guess that the function only should be called for a valid thread, i.e. a thread that is already created by reading the part of the documentation which mentions the error code. But as this is a non standard function and normally for Posix threads one expects to specify all attributes before spawning a thread (compare also pthread_attr_setname_np()), maybe one should add a sentence in the documentation, stating that this function is only valid for an already running thread. Btw. Is there a reason why the call to pthread_attr_setname_np() is limited to kernel space ?
