Indicator that the next value in the \p extra parameter to
::cuLaunchKernel will be a pointer to a size_t which contains the
size of the buffer specified with ::CU_LAUNCH_PARAM_BUFFER_POINTER.
It is required that ::CU_LAUNCH_PARAM_BUFFER_POINTER also be specified
in the \p extra array if the value associated with
::CU_LAUNCH_PARAM_BUFFER_SIZE is not zero.
