[PATCH v11 05/14] pkt-line: rename packet_write() to packet_write_fmt()

From
larsxschneider@gmail.com <larsxschneider@gmail.com>
Date
Oct 16, 2016, 23:20 UTC
Message-ID
<20161016232038.84951-6-larsxschneider@gmail.com>
In-Reply-To
<20161016232038.84951-1-larsxschneider@gmail.com>
From: Lars Schneider <larsxschneider@gmail.com>

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.
