*
*
* @param command_queue the command-queue in which the read command will be queued. {@code command_queue} and {@code buffer} must be created with the same OpenCL context.

*
* @param command_queue the command-queue in which the write command will be queued. {@code command_queue} and {@code buffer} must be created with the same OpenCL context.

* when the buffer object being written is created with {@link CL10#CL_MEM_USE_HOST_PTR MEM_USE_HOST_PTR}, must meet the following requirements in order to avoid undefined
* behavior:
*
*
* - The host memory region given by {@code (buffer_origin region)} contains the latest bits when the enqueued write command begins execution.
* - The buffer object or memory objects created from this buffer object are not mapped.
* - The buffer object or memory objects created from this buffer object are not used by any command-queue until the write command has finished execution.
*
*
* @param command_queue the command-queue in which the write command will be queued. {@code command_queue} and {@code buffer} must be created with the same OpenCL context.
* @param buffer a valid buffer object
* @param blocking_write indicates if the write operation is blocking or nonblocking.
*
* If {@code blocking_write} is {@link CL10#CL_TRUE TRUE}, the OpenCL implementation copies the data referred to by {@code ptr} and enqueues the write operation in the

* completed, the memory pointed to by {@code ptr} can then be reused by the application.
* @param buffer_offset the {@code (x, y, z)} offset in the memory region associated with {@code buffer}. For a 2D rectangle region, the z value given by {@code buffer_origin[2]}

*

*
* All callbacks registered for an event object must be called. All enqueued callbacks shall be called before the event object is destroyed. Callbacks must
* return promptly. The behavior of calling expensive system routines, OpenCL API calls to create contexts or command-queues, or blocking OpenCL operations
* from the following list below, in a callback is undefined.
*
*
* - {@link CL10#clFinish Finish},
* - {@link CL10#clWaitForEvents WaitForEvents},

*
*
* If an application needs to wait for completion of a routine from the above list in a callback, please use the non-blocking form of the function, and
* assign a completion callback to it to do the remainder of your work. Note that when a callback (or other code) enqueues commands to a command-queue, the
* commands are not required to begin execution until the queue is flushed. In standard usage, blocking enqueue calls serve this role by implicitly
* flushing the queue. Since blocking calls are not permitted in callbacks, those callbacks that enqueue commands on a command queue should either call
* {@link CL10#clFlush Flush} on the queue before returning or arrange for {@link CL10#clFlush Flush} to be called later on another thread.

* noted that receiving a call back for an event with a status other than {@link CL10#CL_COMPLETE COMPLETE}, in no way implies that the memory model or
* execution model as defined by the OpenCL specification has changed. For example, it is not valid to assume that a corresponding memory transfer has
* completed unless the event is in a state {@link CL10#CL_COMPLETE COMPLETE}. One of:
{@link CL10#CL_SUBMITTED SUBMITTED} {@link CL10#CL_RUNNING RUNNING} {@link CL10#CL_COMPLETE COMPLETE}
* @param pfn_notify the event callback function that can be registered by the application. This callback function may be called asynchronously by the OpenCL
* implementation. It is the application's responsibility to ensure that the callback function is thread-safe.
* @param user_data will be passed as the {@code user_data} argument when {@code pfn_notify} is called. {@code user_data} can be {@code NULL}.
