question on select: How big can the empty buffer space be before select returns ready-to-write?

From: Ben Greear (

For instance, it appears that select will return that a socket is
writable when there is, say 8k of buffer space in it. However, if
I'm sending 32k UDP packets, this still causes me to drop packets
due to a lack of resources...

Is there any IOCTL that can tell select how much space to require
before it thinks a socket is writable?

Many thanks,
