To release a memory object, call the function
The memobj reference count is decremented.
CL_SUCCESS if the function is executed
Otherwise, it returns one of the following errors:
CL_INVALID_if memobj is not a valid memory object.
CL_OUT_if there is a failure to allocate resources required by the OpenCL implementation on the device.
CL_OUT_if there is a failure to allocate resources required by the OpenCL implementation on the host.
OF_ HOST_ MEMORY
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. If memobj is a buffer object, memobj cannot be deleted until all sub-buffer objects associated with memobj are deleted. Using this function to release a reference that was not obtained by creating the object or by calling clRetainMemObject causes undefined behavior.
