From 434389deb193016464702b25af2b79bb5c6fd098 Mon Sep 17 00:00:00 2001 From: Christian Couder Date: Mon, 8 Aug 2016 23:03:21 +0200 Subject: [PATCH] builtin/apply: make write_out_one_result() return -1 on error To libify `git apply` functionality we have to signal errors to the caller instead of exit()ing. To do that in a compatible manner with the rest of the error handling in "builtin/apply.c", write_out_one_result() should just return what remove_file() and create_file() are returning instead of calling exit().
