|clEnqueueMarker is deprecated by version 1.2.
command_queue is a valid host command-queue.
event returns an event object that identifies this command and can be used to query or wait for this command to complete. If event is
NULLor the enqueue is unsuccessful, no event will be created and therefore it will not be possible to query the status of this command or to wait for this command to complete. If event_wait_list and event are not
NULL, event must not refer to an element of the event_wait_list array.
The marker command waits for all commands previously enqueued in command_queue to complete before it completes. This command returns an event which can be waited on, i.e. this event can be waited on to insure that all previously enqueued commands, queued before this command to command_queue, have completed.
CL_SUCCESS if the function is successfully
Otherwise, it returns one of the following errors:
CL_INVALID_if command_queue is not a valid host command-queue.
CL_INVALID_if event is
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.
