   3 lssek:   Probably should be __wur but lseek(fd,SEEK_SET,0) will succeed if
   4          the descriptor is fine.
   5 lseek64: same
   6
   7 setuid:  will always succeed given correct privileges, so there might

   9 setreuid: same
  10 seteuid: same
  11 setgid:  same
  12 setregid: same
  13 setegid: same

  23 fseeko:    likewise
  24 fgetpos:   similarly
  25 fsetpos:   likewise
