From 75da80b29556e6dbbba21e5297ca440e475f65cb Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Fri, 17 Jul 2009 11:41:02 -0600 Subject: egl: Support per-thread info. This commit introduces a "current" system to manage per-thread info. It uses TLS, if GLX_USE_TLS is defined, or pthread, if PTHREADS is defined. If none of them are defined, it uses a dummy implementation that is just like before.
