Hi,
I'm trying to make a game using ndk. I use glMapBufferOES to update buffer data. However, the function returns NULL and 0 is returned by glGetError as well(which means no error is generated by opengl). Has anyone been able to use this function? is this be a bug?

I just found out that glMapBufferOES is not supported. I thought glMapBuffer is included in vertex_buffer_object extension (on desktop version of OpenGL it is). But, on OpenGL ES it's in a different extension called GL_OES_mapbuffer.
