From 81c634e94f2fef0cec295f7554080c82bd6aeeb7 Mon Sep 17 00:00:00 2001 From: Lars Schneider Date: Sun, 16 Oct 2016 16:20:29 -0700 Subject: [PATCH] pkt-line: rename packet_write() to packet_write_fmt() packet_write() should be called packet_write_fmt() because it is a printf-like function that takes a format string as first parameter. packet_write_fmt() should be used for text strings only. Arbitrary binary data should use a new packet_write() function that is introduced in a subsequent patch.
