5.9. Including Structure Data Types as Arguments in OpenCL Kernels

Pass structure parameters (struct) in OpenCL kernels either by value or as a pointer to a structure.
Attention: The __global struct argument points to a buffer that must be created in the host program to store the structure. To prevent pointer aliasing, include a restrict qualifier in the declaration of the pointer to the structure.
