Jamey Sharp (May 01 2023 at 16:02):I don't know about the WASI side of this question, but it looks to me like POSIX only allows you to set your desired thread attributes before creating the thread, and the getter functions are so you can find out what you previously set in the attributes object you're constructing. As you've noted, pthread_getattr_np for finding out what your thread actually got is a GNU libc extension.
