wow, two errors in two sentences. let me try again. it will tell you wether it wrote out everything. on non-blocking sockets you have to account for partial writes. also I suggest reading usr.sbin/bgpd/buffer.c, especially buf_write (using write) and msgbuf_write (using sendmsg, but logic is teh same). -- BS Web Services, http://www.bsws.de/ OpenBSD-based Webhosting, Mail Services, Managed Servers, ...
