From 725149beab088b1368cc01aa3f1a7845db14132d Mon Sep 17 00:00:00 2001 From: Christian Couder Date: Sun, 4 Sep 2016 22:18:28 +0200 Subject: usage: add get_error_routine() and get_warn_routine() Let's make it possible to get the current error_routine and warn_routine, so that we can store them before using set_error_routine() or set_warn_routine() to use new ones. This way we will be able put back the original routines, when we are done with using new ones.
