From 00d5dad56ff30102fa270832981a837b2f28155c Mon Sep 17 00:00:00 2001 From: Jesse Hall Date: Thu, 12 Jan 2017 14:56:17 -0800 Subject: [PATCH] dlext_namespace.h: Declare android_get_LD_LIBRARY_PATH This allows clients creating their own namespace do so by modifying the default library path, rather than hardcoding it multiple places in the system.
