|  | lssek:   Probably should be __wur but lseek(fd,SEEK_SET,0) will succeed if | 
|  | the descriptor is fine. | 
|  | lseek64: same | 
|  |  | 
|  | <stdio.h>: | 
|  |  | 
|  | setvbuf:   if stream and buffer are fine and other parameters constant, | 
|  | it cannot really fail. | 
|  | fseek:     see lseek | 
|  | fseeko:    likewise | 
|  | fgetpos:   similarly | 
|  | fsetpos:   likewise | 
|  |  | 
|  |  | 
|  | <stdlib.h>: | 
|  |  | 
|  | atexit:    it is guaranteed that a certain number of handlers can be | 
|  | registered, so some calls might need not be checked | 
|  | on_exit:   same | 
|  | random functions:  one might want to discard a number of results.  In any | 
|  | case, no security problem | 
|  |  | 
|  |  | 
|  | putenv:    probably SHOULD be marked, but we'll wait a bit. | 
|  | setenv:    likewise | 
|  | unsetenv:  likewise | 
|  | clearenv:  likewise |
