POSIX says:
http://pubs.opengroup.org/onlinepubs/9699919799/functions/writev.html
If fildes refers to a regular file and all of the iov_len members in the
array pointed to by iov are 0, writev() shall return 0 a
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 sa

Thanks. Although I could not see it in ViewVC -- the page stops loading at the
"configure" script.
Anyhow, I suppose that check_iovec still returns EINVAL for count==0 in any
read functions: simply returning
"tot"==0 means EOF in many (if not all) of them.

As a workaround you can use
