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_NOT_ACQUIRED_KHR if memory objects in mem_objects have not previously been acquired
           using clEnqueueAcquireD3D11ObjectsKHR, or have been released using clEnqueueReleaseD3D11ObjectsKHR
           since the last time that they were acquired.

       •   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.

       resources.

Notes

        1. OpenCL Specification
           page 110, section 9.11.7.6 - Sharing memory objects created from Direct3D 11...

The Khronos Group                                  11/18/2024                         CLENQUEUERELEASED3D1(3clc)

Parameters

num_objects
           The number of memory objects to be released 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 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
