From 7c4ab60f18f5257d37164df0ae0951ece4425b02 Mon Sep 17 00:00:00 2001 From: Alex Bennée Date: Wed, 23 Jun 2021 11:27:48 +0100 Subject: plugins/api: expose symbol lookup to plugins MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is a quality of life helper for plugins so they don't need to re-implement symbol lookup when dumping an address. The strings are constant so don't need to be duplicated. One minor tweak is to return NULL instead of a zero length string to show lookup failed.
