Errors
Returns CL_SUCCESS returns CL_SUCCESS if the function is executed successfully. If num_objects is 0 and
mem_objects is NULL then the function does nothing and returns CL_SUCCESS. Otherwise it returns one of
the following errors:
• CL_INVALID_VALUE if num_objects is zero and mem_objects is not a NULL value or if num_objects > 0 and
mem_objects is NULL.
• CL_INVALID_MEM_OBJECT if memory objects in mem_objects are not valid OpenCL memory objects or if
memory objects in mem_objects have not been created from Direct3D 11 resources.
• CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue.
• CL_INVALID_CONTEXT if context associated with command_queue was not created from a Direct3D 11
context.
• CL_D3D11_RESOURCE_ALREADY_ACQUIRED_KHR if memory objects in mem_objects have previously been acquired
using clEnqueueAcquireD3D11ObjectsKHR but have not been released using
clEnqueueReleaseD3D11ObjectsKHR(3clc).
• CL_D3D11_RESOURCE_ALREADY_ACQUIRED_KHR when any of mem_objectsare currently acquired by OpenCL.
• CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_event_in_wait_list > 0, or
event_wait_list is not NULL and num_event_in_wait_list is 0, or if event objects in event_wait_list
are not valid events.
• CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL
implementation on the host.

Parameters
command_queue
A valid command-queue.
num_objects
The number of memory objects to be acquired in mem_objects.
mem_objects
A pointer to a list of OpenCL memory objects that were created from Direct3D 11 resources.
num_events_in_wait_list, event_wait_list
Specify events that need to complete before this particular command can be executed. If
event_wait_list is NULL, then this particular command does not wait on any event to complete. If
event_wait_list is NULL, num_events_in_wait_list must be 0. If event_wait_list is not NULL, the list
of events pointed to by event_wait_list must be valid and num_events_in_wait_list must be greater
than 0. The events specified in event_wait_list act as synchronization points.
event
Returns an event object that identifies this particular command and can be used to query or queue a
wait for this particular command to complete. event can be NULL in which case it will not be
possible for the application to query the status of this command or queue a wait for this command to
complete. If the event_wait_list and the event arguments are not NULL, the event argument should not
refer to an element of the event_wait_list array.
