WUR-REPORT

   1 <unistd.h>:
   2
   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
   8          be places which don't check for it.
   9 setreuid: same
  10 seteuid: same
  11 setgid:  same
  12 setregid: same
  13 setegid: same
  14 setresuid: same
  15 setresgid: same
  16
  17
  18 <stdio.h>:
  19
  20 setvbuf:   if stream and buffer are fine and other parameters constant,
  21            it cannot really fail.
  22 fseek:     see lseek
  23 fseeko:    likewise
  24 fgetpos:   similarly
  25 fsetpos:   likewise
  26
  27
  28 <stdlib.h>:
  29
  30 atexit:    it is guaranteed that a certain number of handlers can be
  31            registered, so some calls might need not be checked
  32 on_exit:   same
  33 random functions:  one might want to discard a number of results.  In any
  34            case, no security problem
  35
  36
  37 putenv:    probably SHOULD be marked, but we'll wait a bit.
  38 setenv:    likewise
  39 unsetenv:  likewise
  40 clearenv:  likewise
  41
  42 mbstowcs:  probably SHOULD be marked
  43 wcstombs:  likewise
  44
  45 ptsname_r: probably SHOULD be marked
