Definition at line 594 of file driver_opengl_vertex_buffer_hard.cpp. References _VertexArrayRange, and _VertexPtr. void * NL3D::CVertexBufferHardGLATI::lock (    )  [virtual]   Lock the entire VertexBuffer. The returned buffer is a write only buffer. (undefined result if you read it). Write note: for VRAM VertexBufferHard, you should write only one time, to init. for AGP VertexBufferHard, you should write sequentially to take full advantage of the write combiners. Returns: the adress of the vertex 0. Use getVertexSize(), get*Off() ... to access any part of this VertexBuffer. Implements NL3D::IVertexBufferHard. Definition at line 602 of file driver_opengl_vertex_buffer_hard.cpp. References _RAMMirrorVertexPtr. void NL3D::CVertexBufferHardGLATI::unlock (  uint    startVert, uint    endVert )  [virtual]   Same as unlock() but give hints to driver on vertices that have changed. Used by ATI-OpenGL drivers. NB: driver may still ignore this information, and so take into acount all vertices Parameters: startVert  the fisrt vertex to update endVert  the last vertex (not included) to update => numVertices= vertEnd-vertBegin. Hence unlock() as the same effect as unlock(0, getNumVertices()); Implements NL3D::IVertexBufferHard.
