From 126b35bd3acbf486471879531cd2e6f446b14497 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Tue, 29 Dec 2009 15:09:16 -0700 Subject: mesa: implement indexed glGet functions The functions are _mesa_GetBooleanIndexedv(), _mesa_GetIntegerIndexedv(), and _mesa_GetInteger64Indexedv(). These will be called from API functions such as glGetBooleanIndexedvEXT() and glGetBooleani_v(). Only the GL_BLEND query is supported at this time. --- src/mesa/main/get.c | 74 ++++++++++++++++++++++++++++++++++++++++++++++ src/mesa/main/get.h | 9 ++++++ src/mesa/main/get_gen.py | 77 +++++++++++++++++++++++++++++++++++------------- 3 files changed, 140 insertions(+), 20 deletions(-) diff --git a/src/mesa/main/get.c b/src/mesa/main/get.c index 07507414d7..aff67466bc 100644 --- a/src/mesa/main/get.c +++ b/src/mesa/main/get.c @@ -7434,3 +7434,77 @@ _mesa_GetDoublev( GLenum pname, GLdouble *params ) params[i] = (GLdouble) values[i];
