Old notes on functions that should maybe have warn_unused_result annotations

The text below was formerly in the file WUR-REPORT in the source tree. It has not been updated since 2012.


lssek:   Probably should be __wur but lseek(fd,SEEK_SET,0) will succeed if
         the descriptor is fine.
lseek64: same


setvbuf:   if stream and buffer are fine and other parameters constant,
           it cannot really fail.
fseek:     see lseek
fseeko:    likewise
fgetpos:   similarly
fsetpos:   likewise


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

mbstowcs:  probably SHOULD be marked
wcstombs:  likewise

ptsname_r: probably SHOULD be marked
