In OpenCL, memory objects are represented by cl_mem data structures, and they come in two types: buffer objects and image objects. If the memory object is intended to contain pixel data, you should create an image object. In all other circumstances, you should place your data in a buffer object. We’ll look at buffer objects first.

Whereas clGetImageInfo provides information about image objects only, you can obtain information about image objects and buffer objects with clGetMemObjectInfo. Its signature is as follows:
