glInvalidateBufferSubData: man4/glInvalidateBufferSubData.xml
glInvalidateBufferSubData invalidates all or part of the content of the data store of a buffer object. After invalidation, the content of the specified range of the buffer's data store becomes undefined. The start of the range is given by offset and its size is given by length, both measured in basic machine units.
