Yes (and again after getting your reply to be sure). Also note that the
version of `strerror_r` that returns a char* is GNU which is allowed to
(and does) return a static char*, thus ignoring __buf (the NULL param).

If you'd like to test, compile the following with -D_GNU_SOURCE:

#include <string.h>
#include <stdio.h>
#include <errno.h>

int main() {

  printf("%s\n", strerror_r(EBUSY, NULL, 0));

  return 0;
}

"Device or resource busy"
