Subject: [PATCH v2 07/11] ref-filter: introduce align_atom_parser()
Date: Wed, 16 Dec 2015 20:59:58 +0530 [thread overview]
Message-ID: <1450279802-29414-8-git-send-email-Karthik.188@gmail.com> (raw)
In-Reply-To: <1450279802-29414-1-git-send-email-Karthik.188@gmail.com>
Introduce align_atom_parser() which will parse an "align" atom and
store the required alignment position and width in the "use_atom"
structure for further usage in 'populate_value()'.
