From 6079675bdb652045eff48880b0d9938b3e7e79ad Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Wed, 20 Mar 2019 11:39:40 +0100 Subject: make use of OTC_GLOBAL when allocating library-internal contexts As libosmcore is now managing the global talloc contexts, there's no point in having APIs where the user tells the library about which talloc contexts to use for a given sub-system.
