  kernel : _cl_kernel/c
  param_name : _cl_kernel_info/c
Returns the size of param_name field of the argument(s). Calls clGetKernelInfo with values for param_value_size and param_value such that param_value_size_ret is queried.

  param_name) → _cl_uint/c
  kernel : _cl_kernel/c
  param_name : _cl_kernel_info/c
Returns the value associated with param_name for the argument(s). Implemented by clGetKernelInfo with param_value_size set to (ctype-sizeof _cl_uint) so that the value is queried. Valid param_names are '(CL_KERNEL_NUM_ARGS CL_KERNEL_REFERENCE_COUNT).
