When it isn't documented in man pages or info pages, the headers are the only
documentation.  And the headers clearly document that you must not call it with
NULL:

/* Get thread name visible in the kernel and its interfaces.  */
extern int pthread_getname_np (pthread_t __target_thread, char *__buf,
                               size_t __buflen)
     __THROW __nonnull ((2));

/* Set thread name visible in the kernel and its interfaces.  */
extern int pthread_setname_np (pthread_t __target_thread, __const char *__name)
     __THROW __nonnull ((2));
