/*! \defgroup API_Running_Drivers Running Drivers

\struct starpu_driver
structure for a driver
\ingroup API_Running_Drivers
\var enum starpu_worker_archtype starpu_driver::type
    Type of the driver. Only ::STARPU_CPU_WORKER, ::STARPU_CUDA_WORKER
    and ::STARPU_OPENCL_WORKER are currently supported.
\var union starpu_driver::id
    Identifier of the driver.

\fn int starpu_driver_run(struct starpu_driver *d)
\ingroup API_Running_Drivers
Initialize the given driver, run it until it receives a request to
terminate, deinitialize it and return 0 on success. Return
<c>-EINVAL</c> if starpu_driver::type is not a valid StarPU device type
(::STARPU_CPU_WORKER, ::STARPU_CUDA_WORKER or ::STARPU_OPENCL_WORKER).

This is the same as using the following functions: calling
starpu_driver_init(), then calling starpu_driver_run_once() in a loop,
and finally starpu_driver_deinit().

\fn int starpu_driver_init(struct starpu_driver *d)
\ingroup API_Running_Drivers
Initialize the given driver. Return 0 on success, <c>-EINVAL</c>
if starpu_driver::type is not a valid ::starpu_worker_archtype.

\fn int starpu_driver_run_once(struct starpu_driver *d)
\ingroup API_Running_Drivers
Run the driver once, then return 0 on success, <c>-EINVAL</c> if starpu_driver::type is not a valid ::starpu_worker_archtype.

\fn int starpu_driver_deinit(struct starpu_driver *d)
\ingroup API_Running_Drivers
Deinitialize the given driver. Return 0 on success, <c>-EINVAL</c> if
starpu_driver::type is not a valid ::starpu_worker_archtype.

\fn void starpu_drivers_request_termination(void)
\ingroup API_Running_Drivers
Notify all running drivers that they should terminate.
