From 83feeb195592b533541ff6399c8084e5b7c59677 Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Mon, 25 Apr 2022 15:26:28 -0400 Subject: lib/string_helpers: string_get_size() now returns characters wrote printbuf now needs to know the number of characters that would have been written if the buffer was too small, like snprintf(); this changes string_get_size() to return the the return value of snprintf().
