##

cl_int `clFinish` cl_command_queue command_queue

## Notes

Blocks until all previously queued OpenCL commands in `command_queue` are issued to the associated device and have completed.

`clFinish` does not return until all previously queued commands in `command_queue` have been processed and completed. `clFinish` is also a synchronization point.

## Errors

Returns CL_SUCCESS if the function call was executed successfully. Otherwise, it returns one of the following:

- CL_INVALID_COMMAND_QUEUE if `command_queue` is not a valid command-queue.
- CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.
- CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device.
