Increments the memory object reference count.

cl_int clRetainMemObject ( cl_mem memobj)


After the memobj reference count becomes zero and commands queued for execution on a command-queue(s) that use memobj have finished, the memory object is deleted.


clRetainMemObject returns CL_SUCCESS if the function is executed successfully. It returns CL_INVALID_MEM_OBJECT if memobj is not a valid memory object. clCreateBuffer and clCreateImage2D and clCreateImage3D perform an implicit retain.
