From 9331714787f663a1b46447598a7edf0ebff7d355 Mon Sep 17 00:00:00 2001 From: Andrew Tridgell Date: Sat, 2 Jul 2005 11:12:33 +0000 Subject: r8073: a successful rpc call from ejs! the ejs_echo.c code is the stuff that needs to be auto-generated by pidl. It only does echo_AddOne so far. We also need a table for registering these calls. The code is hard-wired for echo_AddOne for now.
