NAME

       clEnqueueCopyBufferToImage - Enqueues a command to copy a buffer object to an image
       object.

       cl_int clEnqueueCopyBufferToImage(cl_command_queue command_queue, cl_mem src_buffer,
                                         cl_mem dst_image, size_t src_offset,
                                         const size_t *dst_origin, const size_t *region,
                                         cl_uint num_events_in_wait_list,
                                         const cl_event *event_wait_list, cl_event *event);

PARAMETERS

        command_queue
           A valid command-queue. The OpenCL context associated with command_queue, src_buffer,
           and dst_image must be the same.

        src_buffer
           A valid buffer object.

        dst_image
           A valid image object.

        src_offset
           The offset where to begin copying data from src_buffer.

        dst_origin
           Defines the (x, y, z) offset in pixels in the 1D, 2D or 3D image, the (x, y) offset
           and the image index in the 2D image array or the (x) offset and the image index in the
           1D image array. If dst_image is a 2D image object, dst_origin[2] must be 0. If
           dst_image is a 1D image or 1D image buffer object, dst_origin[1] and dst_origin[2]
           must be 0. If dst_image is a 1D image array object, dst_origin[2] must be 0. If
           dst_image is a 1D image array object, dst_origin[1] describes the image index in the
           1D image array. If dst_image is a 2D image array object, dst_origin[2] describes the
           image index in the 2D image array.

        region
           Defines the (width, height, depth) in pixels of the 1D, 2D or 3D rectangle, the
           (width, height) in pixels of the 2D rectangle and the number of images of a 2D image
           array or the (width) in pixels of the 1D rectangle and the number of images of a 1D
           image array. If dst_image is a 2D image object, region[2] must be 1. If dst_image is a
           1D image or 1D image buffer object, region[1] and region[2] must be 1. If dst_image is
           a 1D image array object, region[2] must be 1.

           The size in bytes of the region to be copied from src_buffer referred to as src_cb is
           computed as width * height * depth * bytes/image_element if dst_image is a 3D image
           object, is computed as width * height * bytes/image_element if dst_image is a 2D
           image, is computed as width * height * arraysize * bytes/image_element if dst_image is
           a 2D image array object, is computed as width * bytes/image_element if dst_image is a
           1D image or 1D image buffer object and is computed as width * arraysize *
           bytes/image_element if dst_image is a 1D image array object.

        event_wait_list ,  num_events_in_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. The context associated with events in
           event_wait_list and command_queue must be the same. The memory associated with
           event_wait_list can be reused or freed after the function returns.

        event
           Returns an event object that identifies this particular copy 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.
           clEnqueueBarrierWithWaitList(3clc) can be used instead. 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.

ERRORS

       clEnqueueCopyBufferToImage returns CL_SUCCESS if the function is executed successfully.
       Otherwise, it returns one of the following errors:

       •   CL_INVALID_COMMAND_QUEUE if command_queue is not a valid command-queue.

       •   CL_INVALID_CONTEXT if the context associated with command_queue, src_buffer and
           dst_image are not the same or if the context associated with command_queue and events
           in event_wait_list are not the same.

       •   CL_INVALID_MEM_OBJECT if src_buffer is not a valid buffer object and dst_image is not
           a valid image object or if dst_image is a 1D image buffer object created from
           src_buffer.

       •   CL_INVALID_VALUE if the 1D, 2D, or 3D rectangular region specified by dst_origin and
           dst_origin + region refers to a region outside dst_origin, or if the region specified
           by src_offset and src_offset + src_cb refers to a region outside src_buffer.

       •   CL_INVALID_VALUE if values in dst_origin and region do not follow rules described in
           the argument description for dst_origin and region.

       •   CL_INVALID_EVENT_WAIT_LIST if event_wait_list is NULL and num_events_in_wait_list > 0,
           or event_wait_list is not NULL and num_events_in_wait_list is 0, or if event objects
           in event_wait_list are not valid events.

       •   CL_MISALIGNED_SUB_BUFFER_OFFSET if src_buffer is a sub-buffer object and offset
           specified when the sub-buffer object is created is not aligned to
           CL_DEVICE_MEM_BASE_ADDR_ALIGN value for device associated with queue.

       •   CL_INVALID_IMAGE_SIZE if image dimensions (image width, height, specified or compute
           row and/or slice pitch) for dst_image are not supported by device associated with
           queue.

       •   CL_INVALID_IMAGE_FORMAT if image format (image channel order and data type) for
           dst_image are not supported by device associated with queue.

       •   CL_MEM_OBJECT_ALLOCATION_FAILURE if there is a failure to allocate memory for data
           store associated with src_buffer or dst_image.

       •   CL_INVALID_OPERATION if the device associated with command_queue does not support
           images (i.e.  CL_DEVICE_IMAGE_SUPPORT specified in the table of OpenCL Device Queries
           for clGetDeviceInfo(3clc) is CL_FALSE).

       •   CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL
           implementation on the device.

       •   CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the
           OpenCL implementation on the host.
