Re: fcntl bug


I see, I would concur based on the definition of the error code you quoted. I consulted only my memory just now, since I ran the same general test last week.

According to cygwin at sipxx.com on 8/21/2009 3:56 PM:
It does reject the argument if the upper bound is reached. On the lower
end, the linux man page does not specify that negative numbers are not
allowed as arguments.

But POSIX does (and Linux at least obeys this part of POSIX, whether or not its man page says so):

[EINVAL]
    The cmd argument is invalid, or the cmd argument is F_DUPFD or
F_DUPFD_CLOEXEC and arg is negative or greater than or equal to {OPEN_MAX}
