From 944fe69d03f1fcd6ab680fcb672d06036f89f251 Mon Sep 17 00:00:00 2001 From: Volker Lendecke Date: Mon, 23 Jul 2007 10:52:39 +0000 Subject: r24000: Add message_push_blob() and message_push_string(). The proposed new API convention is to start with a 0 bcc length and then push things step by step. These routines reallocate the outbuf and adjust the length and bcc fields as necessary.
