To retain a memory object, call the function
cl_int clRetainMemObject( cl_mem memobj);
memobj specifies the memory object to be retained.
The memobj reference count is incremented.
CL_SUCCESS if the function is executed
Otherwise, it returns one of the following errors:
CL_INVALID_MEM_OBJECTif memobj is not a valid memory object (buffer or image object).
CL_OUT_OF_RESOURCESif there is a failure to allocate resources required by the OpenCL implementation on the device.
CL_OUT_OF_HOST_MEMORYif there is a failure to allocate resources required by the OpenCL implementation on the host.
clCreateBuffer, clCreateSubBuffer, clCreateImage, clCreateImage2D, clCreateImage3D and clCreatePipe perform an implicit retain.
