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 10 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 an Direct3D 10
           context.

       •   CL_D3D10_RESOURCE_ALREADY_ACQUIRED_KHR if memory objects in mem_objects is not have previously been
           acquired using clEnqueueAcquireD3D10ObjectsKHR but have not been released using
           clEnqueueReleaseD3D10ObjectsKHR(3clc).

       •   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.

Notes

        1. OpenCL Specification
           page 77, section 9.9.7.6 - Sharing memory objects created from Direct3D 10..

The Khronos Group                                  11/18/2024                         CLENQUEUEACQUIRED3D1(3clc)

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 10 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 n 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.
