From 6ab5626b08f37bc5b84c67d0f25e363e0ab0180e Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Tue, 16 Nov 2010 19:10:29 +0000 Subject: sim: dv-sockser: add a write buffer variant Rather than having to bang out chunks of data one byte at a time over the socket interface, add a write variant that accepts an arbitrarily long buffer. This speeds things up considerably when we have many chars to send out at once.
