I know that in Java you can get a positive number less than the full
size as an indication that part of the block was written, and you
must loop to write until you get all of it written (or get an error
return).  At this page, it appears that the same is true of the
write function in C:
http://www.gnu.org/s/libc/manual/html_node/I_002fO-Primitives.html
Quoting from that page:
| The return value is the number of bytes actually written. This may
| be size, but can always be smaller. Your program should always

Isn't that the write function we're calling?  If so, are you
maintaining that the gnu.org documentation of this function is
wrong?
