From: René Scharfe Date: Mon, 14 Jul 2008 19:22:12 +0000 (+0200) Subject: add context pointer to read_tree_recursive() X-Git-Tag: v1.6.0-rc0~40^2~4 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=671f0707212c929533dc6ec9e032faee328e4602;p=git.git add context pointer to read_tree_recursive() 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.
