From 2f6d2a9e27f8582591dc60655f7d7b14d7552bbc Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Thu, 3 Sep 2009 09:41:41 -0600 Subject: mesa: change ctx->Driver.BufferData() to return GLboolean for success/failure Return GL_FALSE if we failed to allocate the buffer. Then raise GL_OUT_OF_MEMORY in core Mesa. --- src/mesa/drivers/dri/intel/intel_buffer_objects.c | 11 ++++++--- .../drivers/dri/radeon/radeon_buffer_objects.c | 9 ++++++-- src/mesa/main/bufferobj.c | 26 +++++++++++++++------- src/mesa/main/dd.h | 6 ++--- src/mesa/state_tracker/st_cb_bufferobjects.c | 9 ++++---- 5 files changed, 41 insertions(+), 20 deletions(-) (limited to 'src') diff --git a/src/mesa/drivers/dri/intel/intel_buffer_objects.c b/src/mesa/drivers/dri/intel/intel_buffer_objects.c index ae6f3064a8..c55c5c426e 100644 --- a/src/mesa/drivers/dri/intel/intel_buffer_objects.c +++ b/src/mesa/drivers/dri/intel/intel_buffer_objects.c @@ -130,9 +130,10 @@ intel_bufferobj_free(GLcontext * ctx, struct gl_buffer_object *obj) * Allocate space for and store data in a buffer object.
