In message <199807271932.NAA05034at_private> "Todd C.

It should at least return EFAULT, which is documented for things that fall outside of the processes address space. However, on FreeBSD the man pages states: [EINVAL] One of the iov_len values in the iov array was negative. [EINVAL] The sum of the iov_len values in the iov array overflowed a 32-bit integer. Even though the values are declared u_int, they seem to be used in the code as signed numbers (maybe that's a problem), so return EINVAL for a number, cast to signed, that is negative seems appropriate.
