Using the link Eric Blake provided, I extract this from the POSIX
specification for writev:

"The iovcnt argument is valid if greater than 0 ..."

So, while the man page is a little off, the response seems
to be correct.  You cold argue, and I might agree, that
POSIX should have allowed a 0 and said writev should just
return 0 in that case, but they didn't ...
