From d9bd4cbb9cce9f872cc4427d1c27a62c6768b12a Mon Sep 17 00:00:00 2001 From: Jeff King Date: Wed, 13 Sep 2017 13:17:57 -0400 Subject: [PATCH] config: flip return value of store_write_*() The store_write_section() and store_write_pairs() functions are basically high-level wrappers around write(). But their return values are flipped from our usual convention, using "1" for success and "0" for failure. Let's flip them to follow the usual write() conventions and update all callers. As these are local to config.c, it's unlikely that we'd have new callers in any topics in flight (which would be silently broken by our change). But just to be on the safe side, let's rename them to just write_section() and write_pairs(). That also accentuates their relationship with write().
