Subject: [PATCH 2/6] add context pointer to read_tree_recursive()
Date: Mon, 14 Jul 2008 21:22:12 +0200 [thread overview]
Message-ID: <487BA764.2060003@lsrfire.ath.cx> (raw)
In-Reply-To: <487B92FC.5030103@lsrfire.ath.cx>
Add a pointer parameter to read_tree_recursive(), which is passed to the
callback function. This allows callers of read_tree_recursive() to
share data with the callback without resorting to global variables. All
current callers pass NULL.
